Social Life at Princeton, Dartmouth and Stanford

<p>It goes without saying that all three of these universities provide a phenomenal undergraduate education. I am interested in the social atmosphere of these schools. I always thought the social life at Princeton would be dead. I am Facebook friends with some kids at Princeton and I'm shocked to see how much fun they are having. Lots of frat party, beer drinking pics. I am certainly not going to school expecting to get drunk every night but I would like to have plenty of social options on the weekend. Any and all info people have on the social climate of these schools is appreciated!!!</p>
