Must-sees on NY, PA

Well if your travels take you along I-88 in NY, stop by Brooks House of BBQ in Oneonta, NY (closed on Mondays).

We've enjoyed Tompkins
Part of Cowanesque Lake when we've traveled North on RT 15.

Clean - easy Lake and great area.

Just one more option,

Letchworth is very nice. If you go south on 390 /pa 15s when you get into Pa stop at the visitor center ( rest stop) they have lots of good info on PA. Traveling south of the rest stop is Rt 6 and the PA Grand Canyon ( Wellsboro) .Going west of Wellsboro on Rt 6 is the PA Lumber Museum( CC Camp info). Getting back on 15 south will take you pass the Little League Museum in Williamsport. Rt 15 s will also take you to Gettysburg. Antietam is also a nice to check out. BTW Pa turnpike is very expensive. Have a nice trip and Safe Travel.

In the Lancaster, Pa area, Strasburg has more railroad attractions per captia than almost anywhere else.

The Baseball Hall of Fame in Cooperstown, NY is popular, and fairly close to some other potential Central NY/Finger Lakes stops. A couple of State Parks and plenty of commercial RV Parks in the area.

Chautauqua Institution in Western NY is a great location. If you are a Lucille Ball fan, you can't miss her home/grave/museum in Nearby Jamestown NY.

I oiled then angle down to southern Pa. Fallingwater (Frank Lloyd Wright's) master piece is a must see. Nearby 40 miles or so is the flight 93 Memorial. I woul then travel on to Gettysburg which has more monuments than any battlefield in the world. An hour east of Gettysburg is Amish country which is worth a drive by, Then on to Philly to see Independence Hall/Liberty Bell/Ephrams Alley/Christ Church plus all the other historic sites. If you like history, you can't miss Philly and Gettysburg.

I forgot to mention the Kinzua Dam area of the Alleghany National Forest. Some great sightseeing and hikes. Look up Kinzua Bridge SP;no camping right there but it's worth a visit.

Actually WNYBob, the OP did mention going to Niagara for "a day or two", so one would have to imagine that he will go to the falls, although I seriously doubt he can see your whole list in "a day or two". ;)

If you are that close, check out the Flight 93 Memorial near Shanksville, PA

I tend to be more of a mountains person so anywhere in northern PA all through upstate NY is beautiful country. Lots to see and enjoy with nature. As mentioned, if you are into history Gettysburg is worth the visit. Also, for a total change and something different than you may be used to, central PA is Amish country. Especially the Lancaster county area. Sometimes its enjoyable to be around that area, hit some Amish farm stands and markets and see things a bit different. Harley tour in York PA is a fun thing for a few hours.
