Everyone knows it I think, Mormon girls are generally pretty. But I'm guessing you get a slightly less crazy student body at Utah than you do at BYU, which is why we went with the Utes for our list.
There are a lot of married students at the U. However, this should not discourage you from trying to find love on campus. It's a big school and that equates to many single people, kind of the strength-in-numbers approach.
28. University of North Carolina at Chapel HillGuys & Girls
Carolina offers many opportunities to meet people of the opposite sex for friendship or something more. There are parties, clubs, organizations, sports, and many communal places that students meet up.
Powder blue is a good color on most girls, and UNC co-eds wear it especially well. They also have a reputation as being slightly less bookish than their Duke counterparts, which, for the purposes of this list anyway, is a good thing.
