This is up for grabs. There are so many clubs and activities that I couldn't even begin to start on which is the most popular. There is something for everyone.
I'm involved with B.U.M.P. the Binghamton Underground Music Project, bringing up and coming and underground musicians to the light of the University Campus for affordable, entertaining, and enriching shows on campus.
Athletic events are definitely popular, but our team pride isn't that high. We have occasional even speakers, but not too many. Theater wise, the Hinman Production Company puts on a few shows a semester I believe and they are quite interesting.
The dating scene is what you make it, just like anywhere in the world. Many people are in relationships, many aren't. It fluctuates in a delicate balance.
My closest friends, who I consider my family at Binghamton were met simply from a couple of mutual friends between my floor and other students I had known previously. It is very easy to make friends at BU if you try.
Two in the morning on a tuesday? Not wise in the first place, but if you're up at this time, you're either leaving the Rathskeller's pong tournament downtown, studying for class/finals in Glenn G. Bartle Library, or just a plain old insomniac.
Every year Binghamton has it's Spring Fling, which is a big spriing semester concert featuring popular artists. Artists such as Drake, Wiz Khalifa, an Weezer have appeared in concert at Binghamton. There is usually 2-3 Concerts per semester at Binghamton University.
Party goers also depends on the people. You can sign up for Chemical-Free housing and never hear someone stumbling in your hall the whole semester. However, the party scenee at Binghamton is most definitely present. Many students work tediously and diligently during the week to reap the benefits of a free weekend to spend at a favorite frat or downtown bar.
Frats are pretty big party wise for freshman and pledges, though they are not a big part on campus. Sororities are even less of a deal than Fraternities.
As of right now, I'm on break, so nothing at school. My last weekend of the Fall Semester? I was busy spending my time in the Library hopelessly cramming for Final exams. A typical weekend for me though consists of spending a night or two out, a day of homework/studying, and a day of relaxing with friends or catching up on rest.
Binghamton always has the opportunity to attend 'Late Nite Binghamton" which is a University sponsored, weekend event that takes place every weekend in the University Union. Activities range from Billiards and Bowling to Karaoke and Video games or movies. Each weekend usually has a different theme, and some even have large party like events.
Off campus you can visit the mall, go downtown, visit University Plaza and get some 5 Guys; quite a number of things really. The Binghamton Senators also play nearby, and are a great AHL Hockey club to watch.
