Tons to Do – Obviously, you are in a college town so there are usually good parties on the weekends. Sometimes hit or miss and its generally BYOB, but at least there's no cover charge and they don't card.
The Beach Bars are fun with a laid back atmosphere, but they are 21+. If you are under age, closer to down town will have clubs and if you can wash off your "X's" you shouldn't have a problem ordering a drink. (Hand Sanitizer helps. Plus not all of the clubs are super hygienic. You might want to be carrying it anyways.)
If you drink too much there are taxis. Its like 10 - 12 dollars depending on where you go, but if you are splitting it with people it really isn't bad. Plus you can get taxi vouchers from the school which helps.
