The whole clan concept struck me when my office relocated from North Capitol Street to 14th Street NW. All of a sudden I got to observe the huge bike numbers using the 14th Street bike lane coming down the hill from Columbia Heights in the morning.
As a group, I found their behavior and traits alot different from those I saw for road and Custis Trail users. The most notable 14th Street trait is shoaling: at a red light with cyclists already waiting, new arriving cyclists go right to the front of the pack. I don’t really see that amongst my clan of road commuters.
