Thanks Norm.

I saw what I think was the same snake the next day. My dog was barking at it and when I came over to check it out the snake went into the pond and disappeared. I hadn't seen my dog with a snake until then and I'm glad he chose to stay back and bark. I worry about him because he usually tries to entertain himself with the local critters and like I said, we have a lot of Cottonmouths.
