Critical Mass on a roll in Chile

'Raging Cyclists' inspired by S.F.'s biking movement

Santiago, Chile -- On the first Tuesday evening of every month, a cacophony of whistles, chants and bicycle bells competes with the noise of rush-hour traffic as the Furiosos Ciclistas snake through the downtown of Chile's capital city. The 400-odd 'Raging Cyclists' -- a hodgepodge of naturalists, environmental activists and cycling aficionados -- are patterned after Critical Mass, the Bay Area group that has sent bicyclists riding through downtown San Francisco on the last Friday of the month since 1992.
