North Alabama is kinda of a regional mix. You're sauce is unique though, and that should make it quite the "Boutique" brand.
On edit, there is a pretty BIG sanctioned BBQ Contest in Decatur and the GC automatically qualifies for the Royal. You might want to make it there this year - you've got plenty of time as it's in September.
The 19th annual Riverfest will be Sept. 13-14, 2013, at Ingalls Harbor in Decatur, Alabama.
I'm sure they have a sauce competition...
