As a child I had an uncle that lived in Moorestown NJ (site of the first multi level shopping mall, i think). We visited them twice and went into NYC both times...once we took a train, the other a trailways bus...so I know we were entering through the Port Authority at least once. What year did they close Penn Station? Where did/do trains from the south go since then? Thought it was the Port Authority too but I might be way off base. I did take the train from Cleveland to NYC once (the trip I went to Little Italy) and enjoyed the ride in from the north through the Bronx and Harlem (although a lot of it was underground, the part of the tracks that were elevated was interesting...and Grand Central was nice to see from the vantage point of being a rail passenger.
