This photo was taken by me at the Houston Arboretum. Many people confuse these for water moccasins or cottonmouths. This snake is harmless.
I took this photo in Ville Platte, Louisiana along Main Street. It is a beautiful quiet little Cajun town. The people were fed up with loud car stereos and sagging pants. They passed a laws, and you now get a $250 bond, and trip straight to jail for violating either law. Every city should have this sign.
