Referring to the campus of The University of Colorado Boulder or CU Boulder, this term is synonymous with lots of partying, beautiful scenery, and overall a good time.
It's a fun and quirky college town consisting of yuppie hippies, award winning bakeries, and crazy college kids.

April 20th is an excellent day to spend on this campus.
