A route linking the eight villages around Southam.

GPX is from parking lot to parking lot.  Essence of the route though is to start at the Mason-Dixon line (MD/PA border) and follow AT all the way to Pine Grove State Park. The route completes at the day use parking lot, and roughly a few hundred yards from the general store which is home of the half-gallon ice cream challenge for thru hikers. This is considered the "easier" part of PA on the AT, but takes one from the typical "north/south" separator to essentially the half-way point on the AT (it varies slightly depending on year).
