Definitely not a moccasin. The head is all wrong. I might be willing to agree on the black racer, but the young ones I've seen about this size (basing size on the rubble and debris) usually have more grey and more defined blotches in the pattern. Still, it could very well be one that has started darkening early... Yeah, I'll go with Juvie Racer that needs to lay off of the tanning booth. It's the only thing that really comes to mind looking at him.

Larry, all snakes have teeth. The rows of teeth in a Gray (or Black) Rat Snake will look like fangs. A Water Moccasin, or Cottonmouth, is a snake of swamps, and does not approach this size. Also, a Cottonmouth has a completely different pattern. Almost all snakes have a white inner lining of the mouth, making them look like a Cottonmouth when alarmed; the Black Rat Snake I caught Tuesday showed a white lining to the mouth while biting me three times (she was very frightened), plus, when looking in the Peterson's Guide, it doesn't look like Cottonmouths make it to Northern Alabama. Of course, people will call me a liar, and say they have seen "Water Moccasins", but these are simply Water Snakes, and are harmless.

It is indeed a Glass Lizard. Find a copy of Peterson's Guide to Reptiles and Amphibians of Eastern/Central North America, and look up the Glass Lizards. Looks to me like an Eastern. I have seen exactly one live one, and it was too fast for me. Called "Glass Snake" and "Joint Snake" due to the ease with which the tail breaks off, sometimes into several pieces. The "old husband's tale" goes that they will break apart at a blow, and reassemble themselves after the attacker leaves.

Garter snake. Not venomous, eats slugs and other things. Don't try to handle them - they can secrete a very smelly substance to make predators go away.
