Eastern Garter Snake. Kanapaha Botanical Gardens, Gainesville, Florida. 2012.
I found this pretty snake coming out of an outdoors bathroom at the Hummingbird Garden at the Botanical Gardens. It stopped and looked at me for a while, then slithered back into the bathroom, where it curled up and hid under a supply cupboard. I think someone is going to have a surprise when they use that bathroom!
