Pedestrian overpass crossing the tracks at Lafayette Street in Santa Clara. I’m not entirely sure what their threat model is, but the thing looks like part of a prison to me.

Shot with the Nikon D70s and the 18-70mm f/3.5-4.5 zoom at 70mm, ISO 400, f/11, shutter 1/160 sec. Contrast, saturation, levels, and highlights adjustments in Aperture.
