My son is a junior and has not had a car since he started at Princeton. He finds it easy to get to NYC and doable to get to Philly using public transportation. Getting around Princeton (outside of Nassau St and the campus itself) presents a greater challenge but he has managed to do it without a car for three years. Here’s a link to the public transportation system they have in Princeton. http://www.princetonnj.gov/public-transportation.html
