Do Plains Garters have black undersides? I found one (95% sure it was one) but it had a completely black underside and I can't find any pics of them with a black underside. It had to be a Plains Garter though because the top looked exactly like every Plains Garter pic.

Sorry, but no pics of it. I was moving a pile of wood and found it so I just moved the Garter to a different area and continued moving the wood.
