Notes:

Came upon this guy while driving out of Everglades National Park, (the position on the road is an approximation) I had gone all the way down to the Flamingo Visitor Center and was on my way back. I stopped to take some shots (first spotting for this species so very exciting). It never rattled, but did compact its body into S-shape kept turning to face me as I moved to take pics.
