I decided to just run with this and here's what I've got so far. Again, I wanted to avoid split conferences as much as possible. I also didn't do the entire west because once you get east of Charlotte, I'm a lot fuzzier on where those schools are. There are probably also some charter schools that will have to be added in here or there. I also didn't mess with the 7A schools except McDowell, let someone from Charlotte or Greensboro figure those out.

Edit-added Lake Norman Charter into SW 4A/3A
Edited again to reconfigure Foothills 3A/2A and added smaller conferences with charters. I think I'm done now.
