In San Francisco, artists are transforming trash into artwork as part of an innovative program at the city dump. Recology, the city's solid waste provider, sponsors an artists-in-residence program; artists scavenge through "junk" the public has thrown away and then use it in their work. Join the artists as they hunt for treasure amid 30-foot tall garbage heaps. And if you dig even deeper around Recology's grounds, you might just run into a hawk or two.
