What is between New York city and Philadelphia?

Answer 1

Lots of stuff, but the main city is Washington, D. C.

That's if you take the scenic route, because Philadelphia (PA) is about 100 miles south of New York City, and DC is about 150 miles south of Philly. Depending on your choice of routes, you might leave New York City by way of the George Washington Bridge, across the Hudson River into New Jersey, with a view of the Palisades on the Jersey side. From there, you would travel south on New Jersey's Garden State Parkway, through the industrial centers of North Jersey, to the farmlands of South Jersey. Passing through some historic sites of the Revolutionary War, you would leave the Parkway at the Camden area exit (the city of Camden, much further down the highway after the exit, is one of home sites of Walt Whitman) and pass the Garden State Park and racetrack on the way to the Jersey side of the Benjamin Franklin Bridge, which would take you into Philadelphia.
