ALT Black-and-white flyer with a gradient of bicycles in a row, "BICYCLISTS!" written above. Text: Reduce Invisibility! Join the New Monthly RIDE HOME TOGETHER! Last Friday of Every Month 1st One: Sept. 25 5-5:30 p.m. Foot of Market St. SF Aren't you SICK & TIRED of having to fight for your life on city streets? Why are we treated like cars by the law, but like obnoxious and unwelcome obstructions by people in cars? WHERE ARE WE SUPPOSED TO GO?! Aren't we doing ourselves and humanity a favor by commuting on bicycle? JOIN US ON THE LAST FRIDAY OF EACH MONTH AND RIDE WEST UP MARKET STREET (Groups will split off to various neighborhoods by their customary routes). Come on your bike and help us all MAKE OUR PRESENCE FELT! (Imagine 25, 500, even 1,000+ bikes heading up Market together!) Sponsored by the San Francisco Bicycle Coalition, Bay Area Bike Action, and the San Francisco Bike Messenger Association MORE INFO: 751-BIKE
