Cap’n,
You must be looking at an old guidebook. The Mountainside Market has closed and is now vacant.
Cooter’s has been sold and is now an antique shop. His store in Gatlinburg is still open, I think.
Almost all hikers who get off the AT at Thornton Gap head west to Luray, not east to Sperryville. Luray has all town services hikers typically need: lodging, restaurants, three supermarkets, Wal-Mart, three pharmacies, hospital, three vets, doctors, dentists, post office, a new outfitter (not up to the level of Waynesboro, Harrisonburg, or Front Royal tho), and a five-screen movie theatre.
