University of Colorado to shut down campus on 4/20

For many years, the University of Colorado was known as one of the largest 4/20 gatherings on any college campus in the United States. Thousands would descend upon Norlin Quad for a peaceful and hazy afternoon of basking in the Colorado spring sunshine (and occasional rain). But starting last year, the University decided to close down the campus to everyone but students and official visitors in an attempt to curb the gathering. Their efforts worked, and much to the dismay of ganja smokers in Boulder the campus is being shut down again this year.
Denver Westword has the rest.
