I was in San Francisco earlier this month for an assignment. I didn't do much photography, but here are a couple of street life shots:
Top: Where are they now... "Supergirl" walks around Market St. to promote a Halloween store.
Bottom: A couple of homeless people on Market St. Note the cats on top of the bags; in the US, even the homeless have pets! To be fair, SF's homeless problem isn't as bad as in other major cities.
