Damn it, I was hoping you could help me!
It was bigger than any ringneck I've seen but it had a partial ring (not really but KIND OF see here:
http://klimp.dk/glown/snaik2.jpg ) and definitely more wrinkly-kinky-weird. Also any black rat snake I've seen that small has been juvenile and those tend to have very different markings.
Apparently rat snakes, as a whole, have a tendency to kink up like that when nervous, but this is the first time I've ever seen it. Also, if you touched this snake, he would smooth out and look like a normal snake (still curved!) before winding himself back up into that kinky thing.
WEIRD.
PS don't do a google search for "kinky snake"
