I got $52 from Newark Penn round trip leaving that date and time frame. My daughter is a student at BU, so has done the trip frequently, train, plane and car. The only time she has done the drive in just under 4 hours each way was when she was flying from our home in NJ to Mexico and realized 12 hours before her flight that she left her passport in Boston, so drove almost 8 hours overnight. Her best friend’s family has a home on cape cod, she’s been there dozens of time, the traffic is always bad. We the most bizarre detour this time adding an extra hour.
