I was last there about 8 days ago Wizard. Definitely saw some rattlesnakes, including the big one that comes down to the Arizona Pool to get some water. A springer instructed all the folks, including a young couple who had put up a tent next to the Arizona Pool (argh), not to bother the snake and that he is a regular, and would avoid all humans on its way back to the rock area where he lives just up from the pools. Which is what the snake did.
Your pictures are great Wizard, always love them and your stories you attach to them. Everyone has a camera down there now, it seems - I found myself in two photos online after getting back from the springs the other week….But it was the weekend!
