As a youngster in jr. high me and a buddy used to go down to an old creek that was infested with water mocassins and would hunt them. Usually with a shotgun or .22 but MANY times when we didnt have any ammo we went down with a long stick and a good knife. We'd find one sunning itself lay the stick on its head and step on the stick. Then While one had it trapped the other would cut its head off. The funnest part was throwing the body into the creek and watching it swim with no head

. Occasionally you would see one hanging in a tree and we'd knock it out of the tree and if it didnt get away we'd do the same with it.
But one day we were at the creek there with this other kid that was always practicing with his wrist rocket slingshot. We were standing on the old bridge about 30 to 40 feet from the water looking down into the creek when this ol mocassin comes swimming out from under the bridge that ol boy pulled up his slingshot aimed and hit that sucker SQUARE in the back with a marble. And it was obvious the snakes back had been broken by the marble we just watched as it tried to keep on swimming. And eventually went under. I couldnt believe the shot. Dont know if the kid could have ever made that shot again but it was a doozy.
I generally dont mess with snakes at all unless they are poisonous or a black snake (which eat our eggs). Our neigbors son last yr was bitten by a copperhead just walking out the door of thier house. Which is why I always wear boots with high tops Got to be careful out here in the country.
