No, when I shot, the sucker flipped over and writhed for a few seconds, then shot down his hole! Couldn't believe he still had enough in him to get away. I'm figuring there is no way he made it long, though.
I was bummed, too...I wanted to get a closer look.
I just took a look at some images of the corn snake...I see the similarities you are talking about, but i got to say, I'm 99.9% sure it was a copperhead. I burned their images into my mind when I was studying up on "things that could kill us" in Kentucky. Made sure the kids seem plenty of images, too.
