San Francisco

I am going to San Francisco for 4 days in July with my Mom and Grandparents. Mr. Foodie may be tagging along. I am trying to plan everything last minute. I am going to fly southwest because they have the best routes and prices for the trip.

Several things I want to do while there:
1. Golden Gate Bridge
2. Tour the harbour or go to Alcatraz.
3. Take awesome photographs with my Nikon D90.
4. Chinatown visit for culinary investigation.
5. Muir Woods tour.

I am doing my travel research to see what I can find. The family will be spending two weeks there but I can't take that much time off from work.

Any suggestions for things to do, see, or eat are appreciated.
