Frizbee and circus tend to be the most popular activities. Circus is great. It's mostly a bunch of nice sub free kids who like to juggle and hang upside down. There are no frats etc on campus, but there are still parties. Housing at Hampshire is set up so that half the students live in dorms and the other half live in on campus apartments called Mods. The parties tend to be in the mods. Personally, i dont like to party, but i never have a hard time finding stuff to do. There is always something going on at one of the colleges. College clubs are usually open to students from all colleges, so if there is a club that you want to participate in, and Hampshire dosn't have it, one of the other colleges probably does.
Their are tons of student groups on campus, but very few of these groups have large numbers. There is a community here, its just not anywhere near as focused as almost anyother school. Because Hampshire is self-driven many students become engulfed in their individual studies and their small cliques largely definied by living space. Hampshire also has a drug reputation, which if you chose too, it can be lived up too. However, it is possible to be sub-free here although I honestly don't think you meet as many people that way (being mostly sub-free myself). Overall, Hampshire people are friendly, fascinating people who tend to get wrapped up in their course of study or pet group/activity.
Any group you want to exist, you can work to start it. Theres everything from bellydancing, and live action roleplaying, to any social justice issue you can imagine. Sports is practically non-existant (soccer, basketball, and frisbee are the only teams I've heard of), but there are a lot of political speakers, and theatrical performances. Theres always something to do or someone to hang out with. I've gone for walks at 4 AM on a weeknight and have found kids hanging out. The towns nearby generally close down pretty early, with the exception of some pizza shops, and so many complain that there is nothing to do.
Ultimate Frisbee. otherwise no real sports teams on campus.... which isnt to say there arent those that play. People leave their doors open, which sometimes bothered me. you'd have to look at them while you walked down the hall, obligated to say hi. but i can be kind of antisocial. Parties are ok... mostly cramped. No frats or sororities. The best is just hanging outside with a few good friends, drinking... smoking... or not. I met my best friends there while in the dorms. We'd have to eat at the dining hall so mostly we'd just complain about the food and diarrhea as ice breakers.
There are a lot of groups and organizations, but they have a lot of the same people in all of them. Many other people dont really ever leave their room. People stay up very late, most of the campus is up until 2am on weeknights and 4am on weekends and you can count on the dorms being noisy for all of those hours. Last weekend I went to six parties and I drank, there arent many people who dont drink or do drugs to be honest, but if you are subfree there is no pressure to be sub-full, but there arent many events that are subfree.
People can be extremely studious, usually a typical weekend for me is studying on Thursday night, maybe smoking weed or just hanging out on Friday night, and drinking on Saturday night. There are usually parties on the weekends, but often its more fun to drink and talk in one persons room. There are a lot of events in the area if you want to get off campus, but during the winter thats really unappealing. Hampshire halloween is a really fun party, as is drag ball.
You don't go to Hampshire if you are not active outside of academics. Everyone is active in everything, its incredible. The atmosphere is very open and friendly usually. Most kids are gay or open to it, so the dating scene can be kind of confusing. There is no greek life. If you say the word fraternity, the students will give you directions to Umass Amherst and tell you not to come back.
Popular clubs include, shotokan karate lead by a surprisingly well known shotokan teacher, the fermentation club that makes beer and cheese and other things, and circus. Theater is popular at Hampshire and there are often student plays. No frats, or sororities, and no sports except for ultimate Frisbee. Their are parties most Fridays and Saturdays at Hampshire.
There is always something going around on Hampshire campus that is either totally organized by, or involving all students. Athletics are not very popular, and are basically there for the athletes to enjoy. Theater ranks among the most popular social events, as do the various musical performances that go on all the time.
Doors are always open. Everyone is really into meeting new people, so that's always helpful in making friends. Hampshire Halloween is the shit; so is Spring Jam. Lots of mod parties to go to, there's always beer around, and I'm not sure what sub-free kids do. Maybe it's Monopoly.
