The best deal in town is definitely PATCO, which is offering free rides from 8 p.m. Sunday through 4 a.m. Monday. If you're trying to get from New Jersey to Philadelphia or vice versa, this is the way to go. And if you've been dying to ride a train across the Ben Franklin Bridge but have balked at the $4.50 round trip, well, Sunday night is a big window of opportunity for you, too.
