Be advised: The 4th Annual World Naked Bike Ride will congregate at 11am between the Ferry Building and the Starbucks on Pier 1 to begin a ride "protesting the global dependency of our society and economies at the hands of the oil cartels." The ride will roll by AT&T Park, Fisherman's Wharf, the Marina, the Lombard Street curves, North Beach, Market Street, and the Lower and Upper Haight.
