Crack on the Sidewalk.
Yesterday, we walked through the Tenderloin area of San Francisco and there on the sidewalk I saw these people sitting in a circle. As we got closer, we could see they were smoking a crack pipe. Their faces were drawn, noses red, and all the life was gone from their eyes. I didn't want to embarrass them by snapping a photo in their faces, so I put the camera to my side and snapped it behind my back, upside down, as I walked away.
