The major groups of students are either: Jocks, Hippies/musically inclined people, art and theater students, and brand-focuses people (i.e. the sorority and fraternity students as well as ones who never really left the high school mentality that looks and clothes make the person).
I never lived in the dorms, as I mentioned above, so I have no knowledge of dorm life.
Tailgating is a large part of the athletic events popularity, but many students do enjoy the sports events in general.
We have a very good theater program and Miller Auditorium brings in many touring Broadway plays as well as musical acts. Students get discount tickets, which enables them to be able to afford going to these shows. We also have a lot of guest speakers.
I actually know my closest friend from back home, but I have met many wonderful people down here.
At 2 am on a Tuesday, you could either go to one of the many 24 hour restaurants, or go shopping at Meijer or something. The bars close at 2 am, so that is out. The Bernhard Center on campus is open 24 hours, so you could go to the computer lab or grab some coffee at a local 24 hour coffee shop. Waldo Library is open until 4 am so that is an option as well.
Each year, there are a number of annual festivals such as Island fest and Irish fest. Also, every month, local businesses downtown open up their doors after hours and participate in something called the "Art-Hop". The local business will host a local artist to display their artwork and they will also usually provide wine and cheese as well.
People party pretty much Thursday-Sunday or any big game/event night as well. We also have a large bar scene.
There are a lot of fraternities and sororities on campus and they are fairly popular.
Last weekend I wrote 4 papers and read about 600 pages worth of stuff for my classes, hah.
On a Saturday night, you could go to the movies, coffee shops, museums and art galleries, go out to dinner and a number of the local restaurants downtown, etc. I do any of these things off campus as well.
