My wife and I were constructing two permanent duck hunting blinds on a 7-1/2 acre wetlands project today when we had an uninvited and unwelcome visitor within 5 feet of us. I've learned to carry my "good snake maker" with me here in TX.

After we got home and I could do the research, this is what we determined it to be.

� Allen Blake Sheldon
Diamondback Water Snake. Water snakes bite when captured, and their bite is
more painful than that of other nonvenomous snakes because of their long teeth . Water snakes feed on fish and amphibians, so they need relatively long teeth with which to grip their slippery prey.
Just glad our two yellar Labs weren't along.
