Wellersburg, PA

Wellersburg is a tiny Pennsylvania borough of 147 people sitting right on the Maryland border in Somerset County. Route 96 runs straight through town, connecting north to Pennsylvania's hill country and south into Maryland farmland. The historic National Road (Route 40) provides east-west access before you turn north on Route 96. Most notable is that the Mason-Dixon Line runs right through the southern edge of town, so you can walk across state lines on a neighborhood street.
