Taken this summer in Union Square in downtown San Francisco.
Southern California, in part because of it's warm weather, has a very large population of homeless people, and I saw many of them as I walked around the large Square looking for interesting street scenes.
One afternoon, I noticed a homeless man sitting against a metal railing. From my angle he was also behind a second portable barrier, which made it seem like he was trapped between the two sets of bars: a visual metaphor for his life.
