Weeds,
From NC, you have a lot of options.... In addition to BWTC, you have options in VA, AL, GA, FL and TN all within a day's drive. Many of the top instructors in the world travel through the southeast regularly. We certainly have several CFS courses a year within your range.
Off the top of my head, Depending on where you are in NC, you might look at:
Firearmz in Georgia
Shootrite in Alabama
Perroni Tactical in Virginia
Take a look at the traveling schedules for various instructors as well.
