Where I live there are water snakes, water dog lizards and beavers. The last time I went fishing there was a beaver slapping its tail against the water to try to scare me away. I wouldn't have the nerve to reach in to feel for a catfish. I would probably reach in and grab a beaver, lizard or snake. I've caught 2 foot long lizards on my trot lines. Would you fish with your bare hands?
