While this isn't the usual way I photograph a person, I photographed this young cyclist's legs a few years ago, near Pt. Reyes National Seashore, in N. California, while conducting a photo workshop. I asked him why he shaved his legs.
"One day, after a group ride, one of the women mentioned that she thought a man's shaved legs looked hot. So did the two women next to her. My next ride, my legs were shaved."
