Ever wonder what a sea of humanity looks like? My friend Jos took this picture Sunday morning around 7 a.m. off Church Street, at the start of NYC's Five Boro Bike Tour. We were there with some 45,000 cyclists, ready to ride 42 miles of car-free roads, including the FDR drive, the BQE, and the Verrazzano-Narrows bridge to Staten Island. Ever wonder what it feels like to be in a sea of humanity straddling a sea of spokes and derailleurs? I'm still trying to get my brain around that one. But it is a strange thing to witness one person tip over on a bike --taking out six others in the process-- and having to just keep moving.
