We have some great games at some great venues here in the bay area but non in the city. The only problems I have is I live in the boondocks of SF, I don't drive and I work a lot, so it's very straining to get to them. If I could find a PFS game INSIDE the city it would reduce my commute to one source of public transportation and that would be a game I could make regularly! So where are all the local games?
This is not an answer, but perhaps prior discussions on the topic will help.
There was also a discussion on the BAPS (Bay Area PFS) yahoo group on the same topic in the last year (search messages for 'SF' or 'San Francisco'). This may be enlightening as well.
Hope you can find time and place to play.
