I live in South East Florida. The photos aren't the best so you'll have to zoom (no one wanted to get near the snake), but they show the body pattern, underbelly, and head. It's not a snake I've ever seen in my yard. I usually get small, thin snakes, but this one was thick and long. When it was killed, I looked in the mouth and saw small fangs, but I don't know if it's venemous.
