Bikes, beer and music galore—it’s Biketoberfest! Offering 35 varieties of beer from 20 West Coast brewers and live performances by Moonalice, Tom Finch Group, Tiny Television, Dogtown Ramblers and the Cradle Duende duo, this annual festival is one-of-a-kind, serving our mass of bike-lovers right in the birthplace of the mountain bike. After a pre-festival group ride from San Francisco or Marin, there’ll be 70 bike exhibitors and a handmade bike show with an array of classic bikes from the good old U.S.A.—you might even catch a glimpse of some of the very first mountain bikes. The kiddos can decorate their bikes at the bike art table and join the parade around the festival grounds while adults wash one (or three) down; get your helmets on and gear up on Saturday, Oct. 12, at FairAnselm Plaza. 765 Center Blvd., Fairfax. 11am. Free; beer tasting $25—$30. 415.272.2756.
