If read correctly, an overnight smoky backpacking permit is just 4$. Question #1 can I continue my section hike beginning within the park boundaries? (Last April I walked from Springer to Clingmans Dome). It will take me 3 days to exit the park. That's 12$ compared to 20$ I was charged as a thru hiker last spring. Is this correct? Question #2 If able to continue nobo can you recommend a cheap shuttle service from Knoxville airport to Clingmans Dome parking lot. Other option is sobo from Hot Springs. Question #3 cheap shuttle choice from Ashville airport to Hot Springs? I called one company and was given a price of $180. This sounds absurd to me. My hike is planned for early August. Any tips would help me a lot. Thanks.
