Critical Mass is a gathering of bicycle enthusiasts that happens every last Friday of the month in San Francisco. On Nov. 27, 2009 I joined them for a ride around town. We gathered at the Embarcadero in the downtown area between five and six o'clock that evening. Then sometime not long after six a few hundred of us left there and rode for about three hours all around the city.
