I've been to events where vendors had an unfair advantage and did price-gouge unconcionably. Most of those events, including movie theaters, I choose not to attend anymore. Did the audience at this year's Woodstock have no way of knowing that they would be taken advantage of? Did the story of $8 Pepsis in 94 not get around? That knowledge would have been enough to keep me from going. If they, the audience, had a problem with this setup, couldn't they choose either to a) not go, or b) try to pressure the promoters to ban price-gouging? It's not like there's some kind of civil right to attend an outrageously commercialized event to begin with and to be treated fairly with respect to prices. There was absolutely no excuse to act like a bunch of animals and criminally destroy property. Let them know what you think of them by not going next time. That will get results.
