There has been an unprecedented growth in users of the AT over the past 10 years. The trend shows every indication that user-ship will at least remain constant and it will probably even accelerate. At what level does it become unsustainable? When will we see more restrictions like the ones in GSMNP? When will we have to purchase a pass to hike it all? And another dam*ed thing, why is the AT so overwhelming popular? Canīt some of us focus on other trails that are just as pretty, just as challenging and just as convenient?
