It is also a pretty easy drive. Have done it many many times. NJ Turnpike to exit 4. Then follow the signs and take 73 into Philly. Granted, I am in Staten Island not far from the Outerbridge so it is closer for me than anyone in the other boroughs, LI, Westchester, etc.
If traffic is flowing I can make that trip in about 90 minutes from New Dorp. Not a bad ride at all.
