Interesting. When a lady friend and I were knocked off our feet by a tremendous bang at the intersection of the AT and the Benton trail on Mooselauke in July a couple of summers ago we immediately noticed our legs were asleep (totally numb) from the knees down. After sitting there worrying for about ten minutes everything came back to a normal feeling and we continued to the summit and out the Glencliff trail.. About 100 feet from where we were knocked down, we observed a freshly stripped tree about ten feet off the trail. The ground along that section of trail looked like it had been roto-tilled.
To date I don't think either of us has suffered any after effects from the incident.
I have heard that we might have acquired super powers from the incident, but so far nothing has arisen.
