With all of the World Series excitement, it's hard to escape the baseball buzz in SF -- but the free events continue as we approach Halloween. 1015 Folsom hosts a free party with rockers Yeasayer working the DJ booth and a handful of local DJs. The International Vintage Poster Fair returns with more than 10,000 posters at Fort Mason and Noe Valley gets dressed up for the Harvest Festival.

Free Weekend Events: 10/26-10/28
