I saw a very beautiful, skinny snake crossing my road. I stopped and ran back to watch him and make sure he did get across the road before my neighbors drove by (I know they would swerve to hit him
) He looked like a very skinny, very silvery cornsnake, but I believe he was either a gray rat or a juvenile black racer. He was only about three feet long, and very slender. I was kicking myself for not having my digital camera with me, but I'll keep it in the van next time.
I was just so excited to see one near my house, since we haven't seen any snakes in the yard for a few years now. We had a lot of rain lately, so I figured some might pop up.

BTW, What area of what state do you live in?.....it does sound like maybe a light colored Gray Ratsnake if it had darker Blotches on that sivery/gray colored background.....juvenile Black Racer's loose their blotched pattern by the time they're three feet long.
