Franklin County, Pennsylvania
Franklin County runs along the Maryland line in south-central Pennsylvania, with Chambersburg as its seat and largest borough, Waynesboro and Greencastle to the south, and farmland on either side of I-81. Warehouse and fulfillment construction at the I-81 interchanges in Antrim and Guilford townships competes directly with active agriculture, so zoning, agricultural preservation easements, and interchange access govern which parcels pencil out.
