I don't really have a response but am not sure how to start my own thread.
I was out in my yard earlier mowing and saw a garter snake right in front of my mower and picked it up as I didn't want it to get caught under the mower. As I was carrying her to the backyard (they go under the deck whenever my dog harasses them so I was going to put her back there so she would be safe) I noticed she had a cut not too far from her tail so i took her in the house and ran some lukewarm water over her and then put her in a bowl with about an inch of water in it and put her out on the deck. She climbed out of the bowl and slithered under the deck. I am hoping that since she was so active she will be all right, but if I see her again (and she's still alive) is there anything more I can do to make sure the cut heals?
