Portland, Ore. --- Hundreds of cyclists going as bare as they dared swarmed the streets of Portland June 10 for the largest naked bike ride in North America. As many as 500 nude or nearly nude cyclists rode for two and a half hours circling downtown to the cheers and jeers of spectators, motorists, and passersby. This year also marked the debut of Portland’s first daytime naked bike ride, which culminated in a group photo shot in the lovely Ladd’s Addition rose garden. Warning: This video contains nudity. (Duh.)
