There is all kinds of stuff to do/see/eat in SF. There's also Yosemite. Ghost town called Bodi. If you go further up north (Where I lived for 7 years) there are gold mines, Lake Tahoe, Reno, Interstate 1. In SF, there should be TONS of bands playing. (If you are into that sort of thing) There is Fisherman's Wharf, Pier 39 and Ghirardelli Square, The Golden Gate Bridge, Alcatraz, Union Square, Cable Cars, Chinatown, Lombard, Coit Tower, Sausalito, Cliff House, Japantown, and a bunch of other places.
