I thought about cropping the cigarette out, but decided to go with the authentic look. The Barbary Coast Trail is a halfway decent walking tour of San Francisco. It covers Union Square, Chinatown, North Beach, and Fisherman's Wharf. Some of the stops are a bit obscure, and I hated waiting for the cable car at the end to take me back to the start because there is always a big line for the cable cars. The entire walk is a decent hike, so don't go on it with someone who is not at least halfway into walking or you'll have to stop every block, it is pretty hilly in parts. Dougan's World has more.
