"Tell me a memory associated with a bicycle." 
Natalie Goldberg, Old Friend from Far Away

There is a nonprofit bike shop in Chicago, Working Bikes, which is only open to the public two days a week. Frequently in the spring, there is a line out the door for the best find, a rehabbed metal-fendered Schwinn for less than thirty dollars. I wasn’t fast enough to grab the green one, I settled on the 1970s brown cruiser.
