"I paddle sometimes 30, or you know, sometimes 70 or 80 miles in a week," estimates Rocco Moses, co-founder of Texas State Tubes.
"For whatever reason, I derive happiness from sliding across the top of water," he said.
All of Moses' best ideas come from the river.
"It’s a thinking laboratory," Moses said.
So the New Braunfels native traded in business attire for a floppy hat and a very worn-in shirt. That was five years ago. During a river paddle in the early years, Moses had a realization.
"Whenever we first started, we said, 'Oh we’re working on the river, we need to clean the river,'" he said.
On any given run day, Moses -- and any other volunteers he can convert to his mission -- can be found doing mother nature's work.
"People have been here like 10,000 years," explained Moses. "This is legitimately, in my mind, an important kind of place and we should treat it accordingly."
The businessman and founder of the Texas River Alliance is also partnering with Greek Life at Texas State to increase awareness and volunteering. Every student that shows up to clean up can tube the river for free next time.
The catch of the day ranges from smaller items such as beer cans to large trailers. Moses found the results satisfying, but he felt it wasn't enough.
It took Moses another visit to San Marcos to bring in his biggest haul yet -- an idea: Cashing in for cleaning up. He envisions a system that pays people an hourly wage to keep the banks and waters clear.
"If people are actually in the position where they’re in between jobs or something’s going on in their own life and they need some money, it’s a way that we’ll have a fund consistently that people will be able to contact us and get work," said Moses.
He, along with help from others, plans to make and sell furniture from logs in the river.
"One hundred percent of this money is used to pay people to clean the river," added Moses. "So the river is kind of fixing itself."
He then hopes to hold fundraisers to auction off the unique pieces. It's a notion not all that unrealistic if you know Moses.
"It's just how I think, I guess," he said.
Because all of his best ideas come from the river.
