I am seeing posts on when AT hikers should get their permits before entering the Smokies. What should be the protocol for getting your permit for the Smokies and where if you are a NOBO BMT thru hiker? DO you need to pick out the sites ahead of time and the dates when you pay your fee online? I know you need to make sure to get a print out of the permit. If I need to pick out dates and places, I suppose I'd have to do it en route rather than before I leave (? If so, where is a good place to do this?). Also wish we could get a designation of a "thru hiker" since we are starting over 50 miles outside the park boundary. Many thanks.
