Portland's bike social ecology is variegated and healthy. BTA activists, Zoobombers, mountain bike trail heads, tall bike clowns, bike mechanics, bike-ped planners, messengers, sprockettes, one speed fat tire hipsters, bike pub crawls, naked rides, midnight rides, bike pirates, Bohemian Grove Cycle Oregonists, fixies, road racers, BMXers, the baby trailer set. I think the ecology may be sustainable too. One way it sustains itself is an event like Filmed by Bike. There is a raffle Friday for an electric (!) bike. The whole event is a fundraiser for the Bike Fair. This will be crazy fun and the 8 minute max films guarantee plenty of variety. Clinton St Theater 7,9 Friday, 5,7 Saturday and 7 Sunday Friday $5-10, Saturday and Sunday $6
