If you can make it the Citrus Porsche Club PCA (Central Fl) is doing a Tour of the Mountains the weekend of Sept 22, 23 and 24 we are doing a bunch of back-roads. We are staying in Hendersonville, NC as a home-base. Let me know if you are game !! I'm driving my 1987 Carrera Targa up along with 25 other Porsche's.
Also if you are near Winston Salem, NC I found this cool looking gas station online. Trying to see if I can make a detour would make a cool photo shoot for your trip !!
