Given the length of this thread and the positive comments about fraternities, I have to be more blunt about Penn State years ago.
It was not unusual to see a bloody and hurt pledge wandering around my street in State College, PA. Looking back, I deeply regret not notifying the police. I attended a Jesuit university that did not allow fraternities, so I was shocked by what I saw.
To @TylerandAce, you do not have to belong to a fraternity to have lifetime bonds with your classmates. I audited classes at the University of Pennsylvania for 11 years (2006-2016), and only remember one Jewish student who belonged to a fraternity. I believe Penn has the most Jewish students of any Ivy university.
Since I do all the reading in courses, it's very easy to get to know the students, despite the large age difference.
