What attractions are good in New York City, Hershey, PA and Philly, PA?

NYC has a lot to do so does Philly, but most of those things have to do with history. If you are looking for more recreation I think you would have to venture out of the cities a bit. Hershey of course is known for the amusement parks and I don't think it is very far from the Amish Country. If you decide to take in the sites of NY and want a day of recreation outside the city try kayaking. A great tour company in that area is Kayak East (you can find them on the web). They can supply everything you need and take you on a beautiful tour. You won't believe how close you are to the citites.
