Antelope Canyon, AZ. I entered the canyon as one of about 200 tourists there at the time, well past the peek photography time slot, having no expectation of pulling any kind of pics out of the experience. In fact, I almost skipped the whole thing to get into page for my first shower after a week of desert camping. I was surprised, however, how well the guides handled the crowds. All other groups seem to disappear (you could still hear them, though) and the guides were very sensitive to photographers and their level of sophistication. My guide always got me and my tripod set up for a good shot and helped the little old lady from japan work her point and shoot - in manual mode - to good effect. He even spoke enough Japanese to communicate with her! Amazing.
