Williams Grove Rd. (SR 2011), .5 mile S of Wms. Grove Park
With its excellent railroad connection, this became the site of the Great Grangers' Interstate Picnic Exhibition, founded 1874 by Robert H. Thomas of the Pennsylvania State Grange. A week's attendance at this annual event was estimated at 100,000 or more by the 1890's. The John Williams House, built about 1799, is nearby.
