So, the Presidio, eh? Lucas calls you hither!
I lived in SF for a few years, and I can say that you really don’t need a car to exist happily there. Even in the Presidio. While it’s certainly a tad removed from the mainstream, you can really walk to bus stops, and Muni is fairly reliable, though the drivers and passengers are typically mentally disturbed.
Keep in mind that if you live in the Presidio, you’re not under the juristiction of the fairly relaxed SF PD. The Presidio is under the juristiction of the park police, AKA the Feds, AKA the Federales, AKA The Man. This can be a bitch if yer caught with illegal substances, get a parking ticket, or are caught speeding.
I’d recommend looking in the Sunset district. Quiet, cheap(er), and not too far from the Presidio. Also, easy access to the ocean.
As for places you should know about: Haight+Filmore = lots of bars. Haight+Ashbury = lots of hippies and drugs if you’re into that sort of thing. Market+3rd = heart of the city. Market+Castro = crotch and anus of the city. This last one is not to be confused with 6th+Market which = the stinking, feces encrusted anus of the city. If there were ever a town in the world that had two anuses (anii?), it is San Francisco.
Also, great flea market Sunday mornings where 101 meets 280 near the Army exit.When you arrive, we should have some sort of QT3 Bay Area get together!
Edit
Oh yeah, I almost forgot to comment on Craigslist: In SF, it’s a heckofa lot different than elsewhere. You may have noticed this by now, but Craigslist is HUGE out here, and cannot even be compared to Craigslist elsewhere. It’s easily twice the size of the next largest Craigslist.
