There'll be speakers, lunch, live jazz, and breakout discussion groups on anti-gentrification, violence prevention, and elections/campaigns. Look how much fun they had last year! $7 if you buy tickets in advance, and $10 at the door

Even if you're not interested in conventioneering, the SFPO is also sponsoring a free candidates' forum for all the supervisorial elections in the afternoon. The format is primarily Q&A from the audience, so go and see if you can make Chris Daly blow his stack!
