Forrest, you're right, but if Laurie's scared of Washington Avenue, imagine the trauma of Port Authority, parts of which are still reminiscient of Taxi Driver even post-Giuliani time.
Crimestick, I'm sure other FOTs could answer exactly, but cab fare over the state line ain't cheap. Cab rates in NJ aren't standardized like in NY, but my guess would be $45 plus tip and toll.
Laurie, I take the F train a lot, and while I have been stabbed on 1,890,000 separate occasions, my 9/11/07 "Best Caller of the Night" prize retroactively saved my life.
And there are lots and lots of cabs lined up by the PATH.
