I'm planning a section hike from DWG, south, to Carlisle in May. I've read about rocky trail conditions along the PA section of the trail. I wonder if those conditions prevail along the entire PA section or wether a specific section, north, south , central is worse / better than the others. I'm not seeing a lot of elevation change along this section so I don't want to assume that there might not be other challenges. Also, has anyone used one of the Harrisburg based Capitol Area transit routes to move from Carlisle back to AMTRAK in Harrisburg ?
