Boulder's 4/20 campus smokeout is infamous, as anyone who attended CU can tell you. Each year for the last decade, a crowd of 10,000+ students, dedicated stoners, once-a-year indulgers, and other Boulder residents have converge on the campus's Ferrand Field to light up in unison on 4/20 at 4:20 pm.

But last week, school officials announced that they're snuffing out the celebration:

To that effect, CU-Boulder plans to bring in a swarm of police officers on Friday to surround the campus and set up checkpoints at key entrances. They intend to prevent unauthorized access to the campus by non-students, and the school said that officers will be issuing tickets for tresspassing that carry fines of $750 and up to six months in jail.

Problem is, marijuana protesters in Colorado are more amped up than ever this year, especially with full legalization on the state’s ballot this fall for the first time ever during a presidential election season. An added complication: Demonstrators have held an April 20 protest at CU-Boulder every year for the last decade with very little resistance from the administration.

Meanwhile, protesters say they're not staying home, a lawyer has filed a restraining order to block the university's police-enforced edict, and everyone's bracing for violence.
