Does anyone know of a good area on the southern PA AT to section hike for 2-3 days? I've done a few day hikes on the AT in VA, however never an overnighter. I did about 6 miles in 2 hours, but that was with a light day pack. Are there a lot of tenting sites in that area or is it mostly campgrounds and shelters? Also, any suggestions on where to park/ shuttles to get back to the car? Thanks!
