I remember getting run off of a golf course a time or two with some friends in my youth. We used to catch red eared turtles, catfish, and other stuff. Used a cast net a time or two.
I also grew up walking distance from the Mississippi river so we would go behind the levee into the batture area and fish back there quite a bit. There were nutria, opossum, beaver, rabbits, snakes, and all kinds of wildlife back there. Used to play paintball back there too.
