Hello,
I think you'd find the following helpful:
http://www.autismsociety-nc.org/
Also, there are many Yahoo Groups dealing with Autism and several are NC specific. Just go to yahoogroups.com and do a search on "autism nc."
You could also call the Autism Society of Mecklenburg County for information. Even though you won't be in that county, it's a very helpful office and they'd likely be able to steer you to more local resources.
Good luck!
Sincerely,
SL
