I will be spending a week in the your area the 2nd week of August.My itinerary is as follows:

two days in Bethesda/DC
one day in Baltimore
one day in Philly (any good places to dine/park near the new ballpark?)
one day in Freehold NJ
one day in Harrisburg Pa
one day in Wilkes/Barre Pa.

I will be taking my wife on this trip, and need some recommendations as far as things to do and places to dine etc. I only have one contact to make in each city, so we will have lots of time to take in the sights.

We have never been to the area before, so all suggestions would be greatly appreciated.
