The free show featuring Wyclef Jean and hosted by the University of Colorado at the Coors Events Center last April was designed to stamp out unofficial 4/20 observations on campus. The concert was open only to students — and once the doors closed, those students would not be allowed to leave the venue for the duration of the entire two-hour show. The result of this draconian restriction? The venue, which holds around 11,000, drew a paltry 400 people...by the most generous guesstimate. Meanwhile, the pot party went on outside.
