I get it, though: trail names symbolize the transition from the old life to the new life, a tangible break from what was to what is. Trail names add anonymity among a new set of comrades thrown together by chance, each independently deciding that this was the time to hike the A.T. The trail name becomes their identity among other hikers after they finish the A.T., and represents the freedom of trail life long after their return to the regular world.
But my humble ‘Johnny’ works just fine. And for me, the best part about hiking the A.T. is not enhancing my identity but losing it in the wild wonder of the woods.
