Marty’s photo of the day #3044: Here’s a photo from my second book, Endangered Edens: Exploring the Arctic National Wildlife Refuge, Costa Rica, the Everglades, and Puerto Rico. I’m holding a brown blunt-headed vine snake. Though mildly venomous, she wasn’t “bitey,” and even if she was, I doubt that she was big enough to break my skin.
