Mile 394 (403), km 649. Hiker hell and heaven within 3 days time. Started after our 3rd zero day in Erwin with sunny weather which in the afternoon turned to really harsh conditions. Heavy rainfall, several hail showers, icy wind and temperatures down to 0 (C). A very cold night at 1250m, the next day up to over 1900m including snow on Roan Mt. No idea to spend an even colder night on the highest shelter of the AT so we continued and got by chance a shuttle back to Erwin we had not hoped for. After a WARM motel night back to the trail with a section hiker couple. Then the best day so far on Hump Mt, great views, clear blue sky and a lot of sun!
