Hey, I'm new here and wasn't too sure if fauna emails you when you some one posts on an ad or not, so I figured I'd try it this way, it's more direct anyway... Your Garter Snake you have posted; I definitely agree it is erythristic, and you shouldn't have to check just your local area... I've seen 2 in the Uwharrie State park (NC), (I don't know how far away that is from you but I promise it's worth the trip) unfortunately both evaded the camera and temporary capture, but there are Garters everywhere down there, a lot with high blue/green tones to them as well... Good Luck with him - Chris
