On our way South to the Pittsburgh area, we stopped to eat lunch in Erie, where the rain stopped & became a little sunny. Then we stayed overnight in Monroeville (near Pittsburgh) Erie so we could see Falling Waters and by sheer luck, Shanksville (9/11 Flight 93).

Erie, PA
10/10
Erie was rather dreary
But lunch was tasty.
After a picture of Admiral Peary’s flagship
We departed— short & hasty.
Falling Waters, PA
10/11
Built in the landscape, clean and bright;
organic architecture* brought to light.
Cantilevered+ levels, three stories high:
a magnificent dwelling against the sky.
Lots of space, a lovely sight—
Thank you, Mr. Frank Lloyd Wright!
Wright built the house right over these falls.
Shanksville, PA
10/11
We saw the sign for Shanksville, Flight 93;
Took a detour to find it, we had to see
this memorial to the 40 brave souls who perished
Worth the side trip, a memory we all cherished. 
The area around Shanksville is sparsely populated, with beautiful rolling hills that are in sharp contrast to the tragedy there.
* Organic Architecture was coined by Wright. Wikipedia defines it as a philosophy of architecture which promotes harmony between human habitation and the natural world through design approaches so sympathetic and well integrated with its site that buildings, furnishings, and surroundings become part of a unified, interrelated composition.
+Cantilevered- buildings projection supported at one end: a projecting structure that is attached or supported at only one end. Falling Waters is an example of a cantilevered structure.
