Bike Summer is an annual month-long celebration of all things to do with bicycles
, occurring in a different north american city every year.
This year, in August 2002, Bike Summer is happening in Portland, Oregon. People from all over the country are showing up and riding around doing cool bike things. There are many many events happening, often 2 or 3 or 4 in one evening! These events include things like depaving workshops, bike repair classes, bike parades, the Bridge Pedal, 2 Bike-in movies (one of which uses bikes to power the projector!), a Portland radical history tour... and lots more!
One of the important things about bike summer is that anyone is free to organize and execute a bike-related event during the month and have it be included in the overall calendar. It's a very decentralized, non-hierarchic organization.
