Must-sees on NY, PA

[bobcouch]

We will be visiting friends on the Ohio/Pennsylvania border in early June, then going to Niagara for a day or two.
After that, we have about a week to 10 days to spend in the New York/Pennsylvania area before heading for home.
I need suggestions for things to see and places to stay (37 foot 5th wheel & prefer full hookups w/50 amps)
Philadelphia and Gettysburg are possibilities, but we're pretty much open for any suggestions.
Thanks

When we were in that area we stayed at Campbell's Camp ground in Campbell. Just outside of Elmira with easy tripe to the finger lakes and Corning.

3X on Letchworth, and if you are into waterfalls, Ricketts Glen in PA is a state park with 22 waterfalls along 7 miles of stream. My favorite state park.

Letchworth campground is quite aways from the falls, electric only, and Ricketts Glen is dry camping, most sites small, but bathrooms with showers.

x2 or whatever on Letchworth SP and Watkins Glen and the Corning Glass Museum. One could very easily spend a few days at Letchworth State Park; it's a quite large park, several miles long.

If you like amusement parks even a little, Knoebels should be on your list; it's a first-rate traditional park and having an adjoining campground is very convenient. (The campground itself is clean and well-kept and well-run, but otherwise ordinary; some of the sites are quite tight.)

Philadelphia does have lots and lots to see. The art institute is fantastic, even if you don't care to re-enact the scene from Rocky. Hershey has some interesting sights, as well, particularly if you like chocolate.

Letchworth State Park. The falls aren't spectacular like Niagara, but they are beautiful and in a more natural setting.

Finger Lakes region. Corning is in the area, and as boring as a glass museum sounds, it is interesting.

If you are interested in old planes or motorcycles, the Glenn H. Curtiss museum is really cool https://www.glennhcurtissmuseum.org/

Very beautiful and scenic area.

Check out the Finger Lakes region of NY. Lots of wineries and cool small towns, good golfing, swimming, marinas where you could rent a pontoon boat, etc. We like Keuka lake SP as a base camp; Watkins Glen SP is very nice but it gets booked up pretty fast.

Adirondacks are nice as well.
