Never seen one here where I live, but a man got bit by a timber rattler earlier this summer about 18 miles or so from me. They seem to prefer the heavily wooded and rocky areas in the north part of the county I'm in. Never heard of one being killed here in farm country, but I would think that they could be around.

I don't like snakes, and if I catch one in and around the yard or the buildings, I don't usually give them a pass unless they're a little garter snake.
