Playboy has made itself the authority on college parties. While the magazine is sliding in the "magazines I read for the articles" rankings, it is still spot on when it comes to its infamous party list. So did your school make the cut? Here are the top 5 winners of 2011.

The list takes into account feedback from students/readers, alumni, campus reps and others. 

1. University of Colorado, Boulder

Why? The school has 50 medical marijuana facilities within city limits and is a craft beer lover paradise. 

2. Penn State

Why? FOOTBALL. And their "Dime a Dozen"hot girls.

3. Arizona State University

Why? Look at the photo above, that's why. That and the annual "Undie Run" pool parties and the fact the tempuratures never dip below 60. 

4. University of Western Ontario

Why? The drinking age is 19, so no more pretending to be some 26 year old from Maine or wherever your fake ID is from. 

5. University of Texas Austin

Why? Hot girls, football and the fact it is in Austin, one of the best music scenes in the country. 

For the rest of the list pick up the May edition of the magazine.
