I helped put on a Peace Festival where I live. I'm the Treasurer for the University of Arkansas Omni, Center for Peace, Justice, and Ecology. And I can tell you first hand- alot of fucking work goes into putting one of those on. We got Earl "Chinna" Smith, the guitarist for Bob Marley and the Wailers to come- it was badass.
Go support the Cause Fest if you live nearby!!!
