Forked tongue

Ok! I have a container garden. It’s elevated on a second floor deck. Snakes don’t fly. How’d he get up here? Motivated! And Colleen saw him. And, she hates snakes! Really hates them! I persuaded him to leave the deck. (See: Pushed him over the edge. I do that to people sometimes too.) In the garden bed below he was crawling away, none the worse for wear, when he was kind enough to stick out his tongue. Glad he made it. How far can a snake fall without injury?
