Lucky you! The only snakes I see are garter snakes and an occasional coral snake which I let live because they are docile and their mouth is so small with fangs at the back of their mouth that they can't deliver venom even if they did bite, which they don't.

I haven't seen many of these around.

I'd wager your rat snakes see you more often than you see them. Every time we notice one, all we see is its tail disappearing into dense cover. It pains us to realize how much our presence terrifies these highly beneficial creatures, but as long as we have neighbors who kill any snake on sight, their fear of man may be justified.
