For those who do not live in NE Tennessee (especially around Kingsport) and SW Virginia, or hiked Erwin lately. Erwin is now home to a Pal's Sudden Service. Probably one of the best burger/hot dog joints in the South.
It's located at:
522 Jonesborough Road
Erwin, TN 37650
(423) 330-6731
Located in town next to the Erwin Linear Trail.
