The best wings place I ever ate it was in Harrisburg. If I can remember the name of it, I'll post it.
I was supposed to go to Harrisburg just prior to Christmas, but we found Gettysburg so interesting we chopped Harrisburg from the itinerary and stayed an extra day in Gettysburg. So I guess my recommendation is head down to Gettysburg. I found it fascinating to roam the battlefield.
ETA: of no particular connection to the OP, but I was really surprised at how much Pennsylvania resembled southern Indiana.
