Interresting article about the Appalachain Trail in the WaPo that goes into some detail about not only the history, but also the changes to the route that have happened over the years for various reasons. Interestingly, at 2,200 miles it's almost 150 miles longer than it was when it was supposedly "completed".

I will probably never hike it. If I ever decide to tackle any sort of long distance through hike it would likely be part of the Pacific Crest Trail instead.
