Hello. I am from the Hickory area (40mi NW of KCLT) and have covered most of the airplanes there. Also, there are not many airplanes flying there aside from the trainers. However, the Statesville Airport (KSVH) is a little closer and usually has much more air traffic but nothing compared to Charlotte. You could also consider Piedmont-Triad in Greensboro but it is a fairly long drive. At that distance in the other direction, you have Colombia, SC and Greenville, SC. Also, Concord, Regl. is a fairly busy regional airport for general aviation. I wouldn't bother with Wilson's (E40) but If you do come by Hickory, I would also recommend Morganton-Lenior (KMRN) nearby. Asheville is a good ways up the road into the mountains, but it is Interstate all the way and does have airline service.
If you have any questions, let me know.
