Has anyone been to SFO recently?

I'm gonna be in San Francisco this upcoming weekend, and I will have all day Sunday to devote to photography at SFO. I don't have to be in the airport until 9:00pm on Sunday night. I am not planning on having a car, but I would love to get out and do some spotting. Any recommendations/ideas/suggestions would be appreciated. Thanks.

I also remember visiting a page for the local SFO spotters, and it included a link to the tide charts so that you could predict whether your shots from that one park would have water or mud in the foreground. I can't find the page anymore. Does anyone else know what I'm talking about?
