This leaderless, grassroots social movement cuts through the noise and inertia of car-clogged urban transportation and teaches us to carve a wedge of our city for our dreams. So says essayist Anna Sojourner in this pushy and irreverent collection of inkworthy social critique and optimistic celebration. Four dozen contributors document, define and drive home the beauty of a quiet ride with a thousand friends, the anarchy of grassroots inspiration, the melodrama of media coverage and the fight for the survival of our cities.
