I also ride a motorcycle, and have noticed that the entire motorcycle world has been split into two main camps, the "sportbike" and the "Harley" crowds. Two two never associate, don't wave, and will completely ignore each other even if stopped right next to each other at a light. Because of this division, neither group has any political clout or the ability to get respect from the non-motorcycling public.
Thank god we bicyclist are too smart for that!!!!
