1:30 a.m.: A vacant street. I ride from shadow to shadow through interims of yellow light. There are no cars at this hour, no noise other than my own pedaling and the faint sound of a train in the distance. The never tiring traffic lights change for no apparent reason as I continue my ride beneath them. An occasional car drives by adding another sound to the night as the hum of their tires fade out of earshot. This is one of the best times to be out on a bike. It is freedom.
