Do you see an optical illusion in this photo. When I look at the wind-sculpted ridges of sand in the bottom left part of the photo, it looks like the light is coming from the left side of the picture. But in fact the light was coming from the right and the proof of that is the shadow of the wirey bush on the right side.

Anyway, I thought that I'd balance the cold and snow photos that I've been posting with something from Mexico. This is about 3 miles south of Playa del Carmen.
