Get a bike
The combination of gas bills, insurance payments, and those bright orange Boston parking tickets can really cut into your party budget. If you leave your wheels at home for the year, not only will you save money, you'll also help stave off the freshman 15 by biking, blading, or just walking around campus.
Try coordinating schedules with friends and turn the trip into a social event. Just remember, if you're traveling on two wheels you may want to invest in a heavy-duty bike lock.
