Yeah, I would like to know what it is too. We don't have anything like that around here. I saw a little snake, about 18" long in the yard a couple days ago when I was mowing. I came around the corner of the house, and there he was...I couldn't stop in time, and I ran over the top of him. Remarkably, he wasn't injured; I went and got my "grabber" that I use to retrieve items from the top garage shelf, picked him up and took him down to the creek. I'm pretty sure he was a little bull snake or some other non-venomous variety. First snake I have seen in my yard (other than the one the hawk dropped on the electric line) in many years.
P.S. From the pics I saw on the internet, looks like he was a little gopher snake.
