The hippy-festival constructed for four days of every year near Eugene, Oregon. Full of old hippies who migrated here in the 70s to live on communes, and their children who grew up with it as a lifestyle. We Eugene folk consider it greatly superior to burning man. However, whatever crazy drug orgies may exist after hours will unfortunately NOT be available to the tourists, because the police watch this place like a hawk. If you manage to get an overnight pass, though, you can get away with much more and it is FUUUN. However, even to those not interested in the scene, going for the day offers a fantastic and safe taste of the hippie experience.
Man, the oregon country fair was so great, I felt reborn after staying. Though that may have been all the shrooms.
