I haven't been there in a while, but aside from what you listed, the ferry building is nice. I like sneaking up in the glass elevators at the sir francis drake hotel as well. excellent view
. I believe the museum/park you are thinking of is Golden gate park, lots of eccentricities there to be seen. Chinatown on a sunday morning is ridiculous if you want to see some of that.
haight is the ex hippy now "trendy" neighborhood next to golden gate park. you could head out to the mission or wander the tenderloin if you're feeling brave and want to get some interesting street shots. Think Pursuit of Happyness, as it was filmed/set in the TL and at the Glide memorial church.
You should also know that it is fairly easy to get to Oakland and Berkeley if you're feeling adventurous. Both I feel have equally notable if not glamorous histories.
I never got to photograph S.F. I spend too much time eating when I go there
if you want to catch non-tourist angles of the bridge, there is a fort, fort point(?) I beleive that sits under the golden gate on the San Francisco side. On the other (Marin) side, there is an old fort that is still open to the public (now that I think about it, I don't know because I never checked) that I used to sneak up to at night with friends to. It feels like you're touching the bridge. I can't remember the name, but it is practically right after you cross the bridge out of S.F. if you checked a map you'd see what I'm talking about. For the east bay perspective, the Damn Brit has some pictures of the east bay that make me homesick. He manages to juxtapose the seedy underbelly that is the Port of Oakland with the city across the bay. I know it is possible to get similar pictures from the Berkeley and Oakland hills, via Tilden park and the access roads, but I couldn't tell you how to get there if you tried. I usually get lost and find myself at an amazing vista.
If you like nature, I think the elephant seal season might be ending at Ano Nuevo park. They have tours there during the winter/spring, but I can't remember the exact season. You could always do the wine country thing too :shrugs:
