Very nice shots, Susan. Great looking snake! I actually like these guys. Wonderful to have around to keep the varmints away. There's one hanging out in the yard now, saw him last weekend. This guy is a bit feisty! Usually they just freeze and sort of crinkle up until you go away, rather than coil like this.
I have heard that rat snakes can help discourage copperheads from being in the same territory. I believe it since I have seen one copperhead in over 20 years on my property. Yet another reason to leave these guys be!
