Sorry, when I plan a trip across the country in only a few days, HELP is the only thing that comes to mind...
I think that we are going to end up doing Chinatown, Twin Peaks, check out Lombard Street, Golden Gate Bridge, and then just wander around downtown. We don't have time for much else as our flight only gets into SFO around 4:30 on Saturday and leaves at 6am on Sunday. Plus we are taking another couple with us and they are pretty short on funds at the moment, so I thought these things would be cool and light on the wallet. Now I just have to figure out how to get around and get to these places...
