After dropping off the Safe Routes truck full of bikes, I rode my skinny tire bike from San Rafael to Sausalito. The bike paths were brimming with cyclists.
Got home, ate lunch. Rode over Tam with my fat tire bike.
CAUTION: epic views
Got home, changed clothes. Rode to the grocery store on the single-speed.
Last time I got in mileage on 3 bikes in one day was Oct 4, 2009 (JBG).
