Life during college is full of opportunity. When else are you going to live in the same building as all of your friends, have free time while everyone is at work from 9 a.m. to 5 p.m., and pull all-nighters to explore the city? You need wheels to get out and carpe diem, but owning a car in college can be tricky—and expensive—between permits, parking, insurance, and gas. If you’re navigating student life without a car, check out all the ways you’re not maxing out on these years. (Feeling bummed out? Don’t worry. Sign up for Zipcar and you’ll have the freedom of reserving a car by the hour or day, so you can hit the road when you want and forget about it when you don’t.)
