Mercer County, Pennsylvania

Mercer County is right on the Ohio border in West Pennsylvania. It has a bit of everything. Rolling hills, farmland, and some decent-sized towns.
The Shenango and Neshannock rivers run through it. They’re great for canoeing when the weather’s nice. Grove City’s outlet mall draws shoppers from all over.
But there’s more to the county than just shopping. Buhl Farm Park in Sharon is a local favorite. It has the only free golf course in the U.S.
