There are parties every weekend but they are all off campus at fraternity houses. Pledges will pick up girls and brothers at their dorms and houses and drive them to and from the parties. No parties happen within walking distance of the school. The fraternity parties are very fun but if you are not in a fraternity or are not a hot girl then you probably won't be at many good parties.
If you are in a fraternity or are a hot girl it is great. The downside is that there are no places on campus where parties/drinking happens. The only night time activity on campus is dorm drinking and watching movies in the cinema. Everyone else gets pledge rides to the fraternities off campus houses and party there. Some clubs and sports teams throw parties as well. Bar scene is pretty good.
best frats: sig ep, sae, phi sig, sig chi, signu. they have parties all the time at their apartments and houses. some houses are better than others but they change every year so
best bars: freshman tips, sophomores/juniors maloneys, juniors/seniors kelly's
tons of fun every weekend.
There aren't many parties that happen on campus. Often times its what happens off campus that ends up being the most fun, but if you have a friend in the junior apartments those parties can be fun if they don't get too cramped.
There is always a party. Underclassmen tend to make their way to the courts or frat houses if they are in Greek life/girls. Upperclassmen graduate to the bars once they turn 21 because Kellys is tough on fakes. There is always a place to drink.
It is really what you make of it. It can be hard for guys to get into frat parties but so many other clubs - like club sports or different organizations like band - also host parties. Its not the type of party seen you'll find at a state school but its definitely still a lot of fun.
