One day while at lunch he stumbled across a turtle in a tank that the restaurant was trying to get rid of, they asked him if he wanted it and after checking to make sure there was no chemicals in the pond that might harm wildlife he stuck the turtle in a small cooler and took it back with him. He brought it to the pond and set it free and it promptly sunk to the bottom but eventually started to move around. That turtle was named Rosie and eventually they brought it a few companion turtles, from there the population started to grow and today they are up to 13 turtles enjoying the pond.
