My son needs to complete the eastern PA section. I intend to support his hike. I'd liked to add to my total A T miles. Are there any suggestions of day hikes, out and back or point to point, just a few miles on somewhat less rocky pieces I can do while he hikes up in the rocks? . . . possibly at the start and finish of his longer day sections? I've hiked both ridges on either side of Duncannon (not the climb east though) and they were fun.
