While walking to the Jefferson Memorial, I heard loud music approaching me from behind. What I saw was part party, part road race. This group of illuminated cyclists (with the occasional motorized skateboard and scooter) took a couple of minutes to pass because of their numbers, not their speed. I asked one member that had stop by the side of the road if this was some kind of flash mob. His reply? “It is like the fight club, what is done in the fight club, stays in the fight club.” Click on the image for a larger view.
