BWebb living in San Francisco, what MUST I do/see?

[BWebb]

As of yesterday, I am officially a resident of San Francisco. Now that I am here, I need to know what are the things I must do, check out, etc. I am somewhat familiar with the city, but I have already realized that there is a ton of stuff to do here that you're not really aware of as an outsider. So, what are things I should check out? This includes stuff that only happens once or a few times a year, as I can constantly check back to this thread. Also, if any of you 2p2ers want to meet up for a drink let me know.
