Okay, so I LOVE my former hometown of Portland, but SF actually knows how to ride a bike.If you haven't shown for TD'F in SF you should f-ing show up. These people; enjoy the ride, revel in the bike-geekness and almost race to the end for beer, food and entertainment. Every ride in Portland I talked about SF's ride. Especially now that New Belgium isn't doing their ride in Portland (as of this year). PLEASE show up, pedal, socialize and smile...
