Uniontown, Pa. is located in Fayette County. My whole family on my Dad's side were from Uniontown. Although I spent many summers there & drove there
nearly every weekend while growing up, I have no idea where that park was.
Fort Necessity, Braddock's Grave, the National Road, Searights Tollhouse, Laurel
Caverns & many more are located here. Washington spent much time in this
area, his first battle with the French, his surrender to the French & Indians at
Fort Neccessity, plus this being a hotbed of resistance during the Whiskey Rebellion.
Found a little information on Shady Grove. It is located in North Union Twp.,
Fayette County. It was originally a trolley park. Trolley parks became popular in the late 1800's & early 1900's when people would take streetcars or trains to an
area for picnics or possibly boating. Kennywood Park near Pittsburgh began as
a trolley park but survived & grew into a large amusement park. Another in my area, Olympia Park , had a large lake & skating area & lasted into the 1940's.
Shady Grove is now popular with a swimming pool and campground open to the public.
