Alligator in the Grass, Everglades National Park, Florida
You can never be too careful walking along a waterway while in Florida. This alligator was hunkered down in the grass, silently watching when I hiked past. After my initial surprise, I got down on the grass too — a safe distance away, of course — and let my telephoto lens do the work.
