Do you live in San Francisco and commute down the Peninsula? Dreamed of bicycling your commute to the South Bay but not sure how to get started? Meet the loosely organized and tightly knit SF2G. SF2G is a group of cyclists in the Bay Area that commutes from San Francisco down the Peninsula to Mountain View and all parts in-between. Come to this SF2G Meet & Greet hosted by the SF Bicycle Coalition and get tips and tricks for mega-bicycle commuting in time to enjoy SF2G’s No Rider Left Behind morning commutes Friday, May 4 and Bike to Work Day, Thursday, May 10. The enthusiastically helpful people of SF2G will make sure you get to work without getting lost, and newbies are always encouraged. Last year over 400 people joined SF2G for the commute on Bike to Work Day, and this year they are looking forward to riding with you! Complimentary bicycle parking will be provided by the SF Bicycle Coalition. Space is limited! RSVP at sfbike.org/mingle.
