Leaving the Presidio Sports Basement at 10:30AM sharp. Five people I know and many I don’t are going.

p.s. If I’m fired up about more biking/exercise/outdoor time after Saturday, on Sunday I might bike to the “Tourist Club” (private Bavarian-style lodge near Mill Valley, three public beer fests a year). It’s about 40 miles round trip. Though I might decide to just take it easy Sunday, or work.
