Do you have any idea how fast a cottomouth can move? You don't "walk" away, thats for sure. I am not and have never been afraid of snakes. I am the first one advocating for leaving the rat snake alone to catch rats. I do have a healthy respect for venomous ones, however, and when a venomous snake is a threat to people something needs to be done. I know you would say they are never a treat to people, but I would beg to differ. Humans and venomous snakes occupying the same immediate area is a recipe for disaster.
