CU officials said in a statement that they're reasoning was less anti-weed, and more “pro-not destroying the campus.” The 12,000-person party had started to disrupt the school's academic mission, according to
MASSIVE NARC Chancellor Phil DiStefano, and the number of mountain hippies swarming the Norlin Quad had grown too large to control. (I'm paraphrasing.)
“While this is not money we are eager to spend, we have to ask ourselves what the costs are to us for having our work disrupted or having a student or bystander injured because we allowed the gathering on the campus,” DiStefano said. He added that the costs this year were mainly given to cops. Last year, fish fertilizer was used to keep kids off the quad. No, really.
Anyway, this is all pretty interesting for one thing: CU-Boulder is consistently named one of the top party schools in the country. And the 4/20 smokeout is arguably that one signature event on campus. Either CU kids will figure out some sort of alternative plan, or say adios to the high state's biggest college party.
