A friend noticed a wine shop on Park Avenue displaying a white bicycle in their window. She said it made her feel creepy, and considered it a strange addition to the display. You know, she said, the Ghost Bike. She then explained that when a biker is killed in traffic, a White Bike is attached to the nearest corner pole, decorated with flowers in remembrance. I said I had been fortunate enough to never experience that. Apparently it is true for other cities, she mentioned Seattle.
