All right, welcome, everyone, to the Innovation Flow Podcast. Thanks for being here today. We have a great guest with us today. Dina Davidson is here. Dina works for Tetra Tech as a municipal operations manager, and she's going to talk to us a little about PDNA and master planning and whatever else we come up with. So thanks for being here, Dina.

Yes. Happy to be here.

Yeah. It's a good day for a podcast.

It is beautiful.

Any day is a good day for a podcast.

That's it.

Well, yeah. I'm your host, Blair Corning. Innovation Flow Podcast is designed to talk about park projects, which is the pilot and research center at South Platte Renew. So we talk about park projects, research innovation that we have going around the park center, and Dina is heavily involved in that. But before we get to any of that, why don't you give the listeners a little overview of what you do, how you got to where you are.

Yeah, so I, as Blair mentioned, I work for Tetra Tech. I'm going on 11 years there now, working in water wastewater treatment, project management. Before that I was with a small site civil firm, and before that, I was doing undergrad and graduate work at CU Boulder. So go Buffs.

Go Buffs.

That's it. Yeah. Yeah. And so just, you know, started working in industrial water treatment, kind of transitioned a little bit to international water treatment, and then kind of focused in on municipal wastewater around 27.

So nice.

Yeah. Loving it so far.

Good. When you were going to school, when you started school, is this what you wanted to get into or did it morph along the way?

I wanted to work in mine water treatment. Both of my folks were miners in Redville, so I always was like, can't somebody do something about those tailings ponds, you know? Yeah. So sort of full circle. Yeah.

Yeah. Well, good. Well, how about hobbies? What do you do? What do you do when you're not treating wastewater design and treatment systems? What do you like to do?

Yeah, all things outdoors, but my second love is volleyball. You can always find me on the volleyball court.

All right, man. That seems like. That seems dangerous to me.

Oh, yes.

All right, well, let's get to the icebreaker question. And I knew this would be hard, so I queued it up before. But what is the best piece of advice you've ever received throughout your life, your career, anything?

Ooh, yeah, it's a heavy one. There's a lot of good answers to this. The one I think I'll offer up today, though, is. So as part of my master's program, I did engineering for developing communities. And there was a heavy focus on never forget the human side of engineering. And always don't lose sight of who you're designing for, who you're in service for. Right. Because there's so many right answers that unless you put that human screen on it, it's probably not suitable for that client, that community, that place. And so just making sure you can get lost in the minutiae and reinventing the wheel and things, but coming back up a level and thinking about why am I here, why am I doing this, and who am I doing this for, really, can help kind of keep you on the right path.

Yeah, that is good. I've seen that, too. It's kind of the difference between a young engineer and a more seasoned one. It seems like a lot of engineers go in, they think it's gonna be all math, all science, all technology, but they forget about the people. So. Yeah, that's good. I like that. I'm gonna learn from that.

Okay.

All right, well, let's get to the topic at hand. First, I wanna talk a little bit about pdna. We have a. Well, I'll let you describe it. The pilot trailer that we have on site. Why don't you talk a little bit about that and talk a little bit about what PDNA is. Most people probably have not heard of this.

Yes, PDNA ElementOp. So PDNA is a shortcut nitrogen removal process in wastewater. And so if we kind of back up and provide a little bit of context around that, Conventional wastewater treatment follows a nitrification and a denitrification pathway to remove nitrogen from the water. As part of the nitrification pathway, you have a couple sets of bugs. Aobs, ammonia oxidizing bacteria, and nobs, nitrate oxidizing bacteria. And together they convert and oxidize ammonia to nitrate. Then you come down the other side and your denitrification pathway, that requires carbon, of course, and you're going from nitrate to nitrogen gas. That's how we get nitrogen out of the water, which is a huge regulatory driver for many wastewater plants, is how low can we go on nitrogen? While that process is super comfortable, super reliable, it does require air and carbon. So then you think about pna, which is partial nitrification Anammox. That cuts off a lot of that, heavily reduces the oxygen, and it all but eliminates the carbon. The problem with pna, though, is.

You.

Really have a hard time maintaining conditions. So PNA introduces a third bacteria into that anaerobic aobs. And so they have to out compete these other bugs that are pretty good scavengers, pretty good fighters. And so you have to maintain and promote conditions that keep those anaerobic AOBs in competition to promote that PNA pathway, which is super hard in a mainstream process. It's typically implemented in side stream, so. So that's where PDA comes in. And that's why PDNA is super cool and exciting, is that it is a shortcut nitrogen process. It's kind of the goldilocks between conventional and pna, if you will, because you still gain the savings on oxygen and carbon. Not as much, but you still get tremendous savings. But you're promoting an environment that's much easier for operators to maintain in the mainstream. And so that's why it's super exciting. You can get to really low nutrient levels and also recognize tremendous savings on your mainstream, which is where the bulk of those energy costs come into play.

Cool. So it's a new kind of bacteria, is it? The PDNA is a new kind of bacteria that takes the place of these aobs and nobs. Puts them out of a job, right? Yeah.

Taking them. Yeah. Unemploying them. That's it.

All right. Is it. How'd they find it? Where'd it come from? Who discovered this new bacteria?

I don't know the answer to that. No, no.

It's probably just in there.

Yeah. I mean, they persist in the environment, so most of the time, it's just about promoting the conditions to cause that biological community to really kind of take over and control the situation. Yeah. So they're here at southpaw. Even though you guys aren't running PDNA, you have those anaerobic AOBs on your D night filters. Now. It's just not the right conditions to promot the PDNA process.

Yeah, yeah. That's similar to the, you know, the bacteria everywhere, the trickling filters or the. The aeration basins. People always ask me, do you bring that in? Do you truck it in? But it's all. It's all here. It's just getting it to grow and getting it happy, giving it room and board and.

That's. Right.

Food. It's kind of like. It's kind of like a kid. It's kind of like a teenager.

Yeah. Needy.

Yeah. All right, well, let's talk about the trailer. There's a big trailer out there that is working with pdna. Let's talk about that. What's going on there?

Yeah, the trailer's part of a larger project with the water Research Foundation, WERF. So this is Project 5183. With WRF, the principal investigators, Brown and Caldwell. There are 20 organizations involved in this project, though, and four pilot test sites, of which South Platte Renew is one of those testing sites. And the goal of this project is really to advance PD and A in the mainstream. So to better understand, you know, how do we promote conditions, what's the design criteria? What are our best practices? While PD and A isn't necessarily new, it is still young. So there's a lot of, you know, energy and excitement around better understanding that and also making it more accessible to the industry. Right. That people are doing it, but there's not guidance around how to best apply this. So that's the broader goal of this WORF project.

Okay, so you're setting up tanks in the pilot trailer there and trying to grow this new side stream bacteria. Where did it come from?

Yeah, so we have. Our pilot trailer has two clarifiers and 12 reactor vessels in it. And our media, we have IFAST media, that's from World Waterworks vendor. And we'll get the PDNA bacteria and media from Hampton Road Sanitation District.

Cool.

Yeah.

Borrowing bacteria.

That's it. Yeah. Shipping them across in their little crates. We call them our Anamox Nurseries.

Nice. So what are you hoping to learn from the experiments?

So, a few things. We obviously want to contribute to the broader goals of the WRF project, of course, demonstrating performance, reliability and things like that. But the way we have our trailer set up is kind of twofold. We're first investigating an aggressive IFAS design. So integrated fixed film activated sludge that also contains the media like PDNA will in the trailer. And so what IFAS is, is it's an intensification process. And what we're trying to do is set up the conditions like I was talking about, promoting those conditions that really help PDNA proliferate using our IFAS reactor in an aggressive kind of design mode to produce the conditions for that bacteria and the next tank down to really maintain those PDNA performance specs. So first, we're going for an aggressive IFAS design and refining that. Second, we're looking at PDNA performance and whether or not we can maintain our nutrient levels and our ethylene goals. To execute PDNA properly, you need kind of an equal parts of ammonia and nitrate going into your PDNA reactor. So we're going to start by learning about that. Can we control that? Is it reliable? And then from there, we'll start optimizing pdna.

Nice. You mentioned intensification in there, which is a hot buzzword or New kind of concept, maybe tell the listeners what, what that means in terms of wastewater treatment or our industry.

Yeah, so intensification is essentially doing more with less. And so as part of this WRF project, there's three configurations of PD and A. This will all loop back. There's a pre anoxic implementation, a post anoxic and a tertiary. So, you know, taking existing infrastructure, existing treatment processes that you have, like tertiary D night filters, if you can implement PDNA on top of those and do more in that same footprint that you have, it's really capitalizing on the investment and the infrastructure that South Platte and its ratepayers have already put forth investments in to maintain. And so it's just doing more with less and trying to find ways that 20, 50 years ago, when infrastructure was put in so that it doesn't go obsolete, you can keep using that and get returns on that infrastructure.

Nice. Well, that kind of leads right into my next question, which is, you know, how does that work? Everything in the trailer with the reactors and the clarifiers, how does that affect things outside of that trailer? How is that going to be in play at the plant level?

Yeah. So South Platte, of course, is demonstrating many things to the broader WRF team with performance, reliability, control strategies, of which there are many for PD and A, and just kind of best practices and operational constraints. It's also an operator training center. Basically, it's how do we refine, how do we really maintain these conditions? This operating scheme that's kind of the first kind of benefit outside the trailer walls is getting operators familiar with what is this new thing we're talking about adding on top of what we have here. Can we handle it? What kind of additional draws on our time and resources might this, you know, require? And then in the case of South Platte, you know, things like IFAs intensifying things like your SCT solid contact tanks, where you do a lot of that kind of biological conversion. Now, if we put the IFAs media in those existing SCTs and intensify them and do more there than what's being done now, it will save South Plat and ratepayers money in the long run because you won't have to build out that infrastructure as many new tanks in the future. So there's kind of savings on tankage for the solids contact tanks. And there's also the potential to take off trickling filters here, which are huge, huge treatment units that require lots of energy. And so working together, there's so many draws on priorities these days and trying to balance all those priorities. But in South Platts case, implementing PDNA could happen on the D night filters could happen by intensifying in the solids contact tanks and promoting those conditions. Or maybe PDA is going to be best suited in a pre anoxic environment. But it can be implemented at South Plat a number of different ways, but all of which have big returns for South Platte and savings.

Nice. Well, that is, yeah, when I think or hear about intensification, this is a perfect example of that. It's like we have the concrete poured. You have a system. How can we make it better? How can we use technology from today to improve on what we thought was state of the art 20, 30 years ago? Well, good. Let's get into, you know, you mentioned the people side in your answer to the best advice you ever got. And I know you're involved in a lot of different organizations and projects throughout the industry and, you know, interact with a lot of different people. Let's talk about that for a little bit. What industry groups and projects have you had the opportunity to be involved in during your career path?

Yeah, starting at cu, I was part of the rmsa, WWA and RMWA kind of student groups, which are local organizations for both the water industry and wastewater industry. Coming into the professional realm, I started volunteering with Water for People and RMWA and was a committee chair for Water for People or leader in Water for people for about 10 years. And then I was fortunate enough to serve on the RMWA executive committee and really get to know a bunch of really tremendous individuals who are kind of movers and shakers and excitement in the water and wastewater industry. And it's really nice to be around that kind of environment, that kind of person who's excited about what they do and passionate and kind of reinjects that, oh yeah, this is why I'm in this industry. Kind of thought so. Did a lot with RMWA and Water for People, volunteered with Engineers Without Borders, both in school and as a professional as well, just to kind of keep tabs on that human side, that humanitarian and trying to do more around the world for the better of everybody.

Did you ever, either through Water for People or Engineers Without Borders, go on any trips or do any projects overseas?

Yeah, well, as part of my master's work, we worked with an NGO in the Amazon called konapac. And so we traveled to some small communities downstream of Iquitos, which is in Peru, in the Amazon, and we worked with them on just kind of vertical water treatment plants and kind of operator training, how to maintain chemical dosing and the whole nine yards when there's no currency there. It's a barter and trade type community. And yeah, so very eye opening, very humbling. Nice, nice reminder of we're so lucky that we have our taps and our toilets and everything else. So, yeah, that was a very eye opening, impactful experience. And we delivered surveys across the communities in Spanish, of course. And so I think we caught most things. I'm sure some were lost in translation, but really got the feel for the community in doing so. 12 different communities and. And just really trying to tailor the operation and capacity building and what's realistic to achieve here.

Yeah, yeah, yeah, I get that sense. I mean, I don't do a lot of international travel, very little, but whenever I talk to him who's come back from a different country, a lot of times I hear stories of, you know, how good our water is, how lucky we have it, you know, water and sanitation services here, which I know most people, including me in this country kind of take for granted when they're, you know, out of sight, out of mind. But it's. Yeah, you don't, you don't appreciate it, I guess, until you go overseas and see what, what else is out there.

Yeah, yeah, definitely.

Well, cool. Let's get back into the. The conversation. I know the PDNA trailer is informing decisions and that ties into the master plan. Tetra Tech was involved in doing the master plan for the South Platte renew facility. So can you talk a little bit about the connection with the master plan and the park project in general?

Yeah, the master plan was a super fun project. And, you know, the challenge with master plans is that the second you call your deliverable final, whatever it is, it's obsolete. Likely the next day or shortly thereafter. Right. Something changes, some regulation happens, some driver happens, and then slowly but surely it becomes more and more obsolete and more and more of a MacGyver tool to try to be a useful document or platform for an organization to use as a planning tool. And so coming into the master plan, the collective team here at South Platte, we knew we wanted to come up with something that would be more of a living tool. And there's a lot of ways to attack that, but we had an idea of what that might look like. And so we basically left the last chapter of that story unwritten, which is an uncomfortable thing to do. You know, in a master plan, you like to lay out your capital improvement plan, your CIP for the next 20 years or whatever your Time frame is that you're planning around. And we, of course, did that, but what we did was we allowed it to be flexible. So there's, of course, dollars in the budget. But there's a lot of different ways that South Platte might get to the end of that 20 years. We wanted to make sure it was, you know, reactionary and could be used over time as things changed. And so we outlined three different management plans that South Platte could kind of tackle for a nutrient standpoint. So there's management plan one. If we're talking about, like, chicken wings, this would be like the mild.

Oh, now you're talking my language. All right, that's right. Now I'm re engaged here.

Yes. Okay. So the mild chicken wing is just enhancing the current process. Right? It's. It's implementing things like PDNA and PNA on the side stream, but really it's just kind of enhancing what's already here. The management plan, too, is. That's like the super spicy habanero chicken wing. Right. This is the new technology, the new primary treatment for AAA alternating activated adsorption. And it's, of course, coupled with other kind of core technologies too. And then kind of the Goldilocks, the just nice medium chicken wing is implementing IFAs. That's Management Plan 3. But we left the gate open so that Southpot Renew could take time to learn about which of these three plans might work well for us. And maybe we need to pivot amongst plans or maybe we need to blend some plans or components of plans together. So it's a super flexible approach. And the idea behind that is trying to responsibly delay decision making when you have the benefit of time. Not everybody does, but in this case, we had some time. Is push those decisions out as far in time as you possibly can so that when you get to that fork in the road and you have to make the decision, you feel confident in that decision.

Yeah. Yeah, that's. It was interesting. I haven't seen one like that. You know, it almost reminded me of, like, if you've ever read those choose your own adventure books. Exactly. It's like a choose your own adventure master plan using park to help you figure out which path to take or which, you know, which page you're gonna flip to. So, yeah, it's. It was different. And I could see the. It would make, I guess, some people uncomfortable because, yeah, scientists are, you know, what's the answer? Where are we going? But also, you see so many master plans get done, and like you said, they're either obsolete or even if they're not, they go on a shelf and gather dust. And they don't really contribute all the time to the, to the decisions or to the organization. So I think the. I think this is a good one because it's got people engaged, it's got, you know, people getting information in order to make decisions. And we'll see how it goes. But it's been fun.

Yes. Yeah, yeah.

All right. You know, with leveraging park in the master plan to make those decisions, what kind of. You mentioned a few here, but what kind of technologies or areas of the plant did you, did you focus in on?

Yeah. So obviously South Platte has this tremendous asset in parc and so kind of coupling with the cip, we developed a kdp.

Okay, you gotta explain these acronyms though. What's the cdp?

Capital Improvement Plan.

Okay.

That's our traditional how we're gonna spend money when we're gonna spend money on what project. The KDP is a knowledge development plan. So this included essentially a very targeted pilot sequencing strategy for South Platte to undertake to try to answer some of these questions. Obviously Nutrients is a big one for South Platte. So that was one that we really kind of circled around and developed a very thoughtful sequencing plan for pilots and using the park to do so. So we talked about delaying that time when you have to make that decision. And as I mentioned, there's so many right answers. And so take this time to execute pilots. The pace of innovation today is just tremendous. Taking the time too to let technology and processes evolve and mature over time and then use these pilots to learn about how does it behave with South Platts wastewater? How can we couple these processes together or not? How do we implement them into our daily O and M with operators and our resourcing. And so we outline those together so that the output of that pilot sequencing and that knowledge development kind of incrementally feeds knowledge into the CIP such that South Platte staff can then manipulate that cip, the Capital Improvement plan that contains the dollars and the planning tool for the organization. You can change that based on what you're seeing. The results of a pilot. Maybe it's, you know, results in the industry of kind of evolving technology over the next five, 10, 20 years. And yeah, so really using that and sequencing out these pilots, of which, you know, IFAS is one, PDNA is another. And so using that time getting all that data to feel good about that decision.

Yeah, that's got to be, that's got to be good for you on the design and engineering side too, to have ongoing research, plant specific to help shape how the designs go and the sequencing goes.

Yeah, exactly. And it's so informative from the planning perspective too, because nothing you put in the ground today is likely going to be relevant in 10, 15, 20 years from now. You have to kind of be able to evolve and be nimble in that regard. So being able to use and implement piloting alongside your normal kind of project implementation plan is tremendously beneficial to manage resources like dollars and energy, of course, but also to manage risk and adopting kind of new technologies or maybe making a change away from processes that are kind of normal and customary for a facility. But yeah, being able to kind of integrate that with your planning is. Is really, really impactful.

Yeah. How was it getting back to the people side? You know, when you went back to a group of design engineers and said, we're going to do a choose your own adventure style master plan? How did you get there on the people side?

Yeah, you know, it was a group effort, whole team effort for sure. But we kind of introduced the idea, Anna and I, to the collective team, Anna Schrader, who works here at South Platte, and we said, we. This idea, you guys, this is going to be a little uncomfortable, but we think it might really pay dividends for us if we kind of think creatively here about how we might move forward in time. And it might also allow us to adopt some innovation versus kind of stick with the old trustee. Right. One thing we kind of said a lot during the master plan is while you might not want to be the first adopter of a technology, you also don't necessarily want to be the last adopter of a technology. Right. Kind of want to kind of ride the average.

I put that in right before it went obsolete.

Right. That's it. Yeah. And there was a lot of traction and a lot of energy around. Hey, yeah, actually, you know, we'd really like something that could be reactive for us. And we have a lot of staff and a lot of energy around piloting and contributing to the industry at large, but also using that knowledge for our benefit here on site. And so there was a lot of energy for approaching it that way.

Yeah. Well, do you think this is the. Do you think you'll see more master plans go in this direction or are you going to patent this? Choose your own adventure idea?

That's it. I would love to patent that. I hope so. It was super fun and really just keeps all the doors open. It's such a flexible way to plan and feel good about kind of setting the stage for really defensible decision making. Right. You have so much data and confidence and certainty around why you might choose something over another thing by the time you get to that decision point in time, that you're feeling really good about it to your boards or your community, whoever might be your body.

Yeah, I think for. What was that you said? The play on the time, the time value of money. What was that related?

So we flipped it on its head and called it the money value of time. For the master planning sake is that take the time now that you have. Don't invest in something that might change in the next 10. If you have five, 10, 15 years before you have to answer a question, take advantage of that time, that money value of that time, to get your answers and get your certainty and follow kind of the pace of innovation and improvements and process such that by the time you get there, you're feeling really good about it. And so, yeah, instead of buying now and trying to figure out how to work with it later, it's taking advantage of that time and building kind of your arsenal of information now such that when you invest later, those dollars have a lot of impact. Dollar for dollar.

Yeah, I like it. The money value of time. Instead of buy now, pay later, you're paying now so you can buy smart later.

That's it.

Man, this is good stuff. All right, Dina. Well, I think, you know, there's PD and A, but I know Tetra Tech is involved in some other or is going to be involved in some upcoming park projects. Can you give us a little teaser, a little insight, a taste of what's coming down the pipe?

Yeah. So we submitted and were successful in getting a grant to explore this AAA process I mentioned earlier.

Not the auto club, right?

No, the Habanero Spicy chicken wing technology. Yes.

And what does that stand for?

AAA stands for Alternating Activated Adsorption. And so it's a primary treatment technology. There's no US installations or US pilots yet, so. So this will be a first, which is exciting. There's approximately 10 installations around Europe doing really well. It really speaks to, like we were talking earlier, there's so many competing priorities for organizations and people. Right? You want to be sustainable and you want to recover resources, but you don't want to spend all your ratepayers money. Right. So there's so many competing priorities. And AAA does a really great job fitting in with the decarbonization paradigm. So trying to use less carbon, put out less greenhouse gases, et cetera. What it does is it moves more carbon into your digesters, more usable carbon, so that you're generating more biogas like you guys do here at Southpaw Renew, so you can get more energy without bringing in any more or different wastewater. It's just diverting carbon in a different way, and then you get to capture that resource and capture that energy, which is pretty cool.

Yeah, it is cool. Cause right now, I mean, it's taking carbon right out of the wastewater itself. Right. So you don't have to add chemical carbon, which a lot of plants, including us, do right now for denitrification. So, yeah, if we can pull that out of the existing wastewater, that's a big savings.

Yeah, yeah. So right now, the trailer's being constructed, or the unit, I should say. It's not really a trailer by the technology developer in Austria. And that'll be shipped to South Platte late summer.

Do they need someone to shepherd it over?

Definitely. I think so.

I can go ship that thing over here. All right, well, that's. So next fall. They're shooting for that.

This fall, 2025.

Okay. That'll be interesting. The first one in the U.S. yeah.

Very excited.

That is the spicy chicken wing.

Yeah.

As you put it.

Yes.

Well, good.

And with all the management plans from the master plan update, South Platte will have been able to pilot all three of those kind of major components between these two pilots, which is really cool.

Yeah, that is cool.

Yeah.

Well, there's a Technology's fun.

Super fun.

Yeah.

Yeah.

I like the choose your own adventure. I like the focus on research and intensification that you've talked about and incorporated into the master plan. And thanks for being here and sharing it with us today, Dina.

Yeah. This was super fun. Happy to be here.

Well, we're not done yet because we have a mad library. Are you familiar with Mad Libs? Yeah, I saw your face. Like, maybe you've had a bad experience with Mad Libs. So give me just quick off top of your head. We got about 10 of these. Give me a place.

Disneyland.

Disney. Okay. Give me a adjective.

Furry.

Furry. I like that. Give me a plural noun.

Dogs.

Alrighty. Give me an animal plural.

Cheetahs.

Cheetahs. And a gross noun.

Booger.

Okay, a few more here. Another adjective and a number.

Let's do squishy.

Squishy. A number 23. Perfect. Two more adjectives.

Tall.

Okay.

And funny.

Funny. All right, we're almost done here. Silly name.

Let's go with dinkle Splat. All right.

I don't know if I can Spell that.

But from my kids movie.

Okay. Splat. I'm trying to spell that. Okay, two more. A random object. No. Three more random object.

A mirror.

I like it. A funny. No. Or just a noun.

Any noun will do. Wastewater.

Okay, I can see you're getting tired out on these, but that's good. I only got one more adjective left.

Okay, let's do spiky.

Spiky. All right. You have just completed the Mad Lib and you can take this back to Tetra Tech and read it to the project team. The story is revolutionizing wastewater treatment.

Okay.

And here's how. Do you want to read it?

Oh, yeah.

Okay, I'll give it to you and you read the revolutionizing wastewater treatment story.

Well, I'm glad I put wastewater in here. So there's nothing that's sort of right. Okay. Scientists at Disney have just unveiled a furry new wastewater treatment method.

I like it.

Using docks. How appropriate. Instead of traditional filtration, they now rely on cheetahs to help break down boogers. Excellent. This process.

This is so juvenile. I love it.

This process is squishy and reduces energy use by 23%.

Wow. That is pretty good.

Said Dr. Dingle. Splat. Plus, it only smells. It smells only tall instead of completely funny. Next, they plan to test the system using mirrors and hope to generate enough power to run wastewater. The future of wastewater treatment has never been so spiky.

Nice. Nice. I wish you would have said spicy on the last one. Spicy could have tied it back to the hot wings.

That's right.

All right, Very good. Thank you for that. Thank you for that Mad Lib and thanks for being on the show again, Dina. It's been been sorry that we had to bring it all down with some juvenile Mad Libs, but the rest of this was really high tech. Good stuff.

I'm here for the Mad Libs and the dad jokes.

All right. Right on. Well, thanks for coming on and we'll have to have you back and check in on that AAA project once that thing kicks off.

Definitely. Happy to be here.

Good. And to the listeners, thanks for listening. If you like this show, give us a five star review on whatever podcast platform you're listening on.
