The best advice I can give is to watch this forum, and read some of the older threads--there is a LOT of great info on here...
Franklin Co. is the rural area NE of Raleigh--OC should be pretty well-accepted in your area, but since I don't have any personal experience OCing there, I can't speak directly to the attitudes of local Law Enforcement, or your Sheriff's department. Rural areas tend to be MUCH ore accepting about OC though, so if Franklin Co fits the general trends of the rest of the state, you probably won't get much attention OCing.
Buy an inexpensive digital voice recorder and carry it all the time. You can get an RCA unit at WalMart for under $35. Voice recorders can be a REAL asset if you do get hassled by some rogue LEO, and the knowledge that you are recording an interaction can go a long way to keep citizens AND LEOs polite, legal, and within the bounds of the law in their interactions.
You need to be VERY familiar with NC law if you're going to OC--we have some weird laws, and the list of "prohibited areas" where you can't carry is long and doesn't really make any sort of logical sense.
Go to the NC DOJ website, and download the "NC Gun Law" booklet. It is a PDF, and has a lot of the basic info you need to know spelled out in black and white. You can also download it from the "Grass Roots North Carolina" website, or view it as an HTML document:
And ask a LOT of questions. We've got some very knowledgeable folks on this forum, and we're more than happy to point you int he right direction.
Good luck, and welcome.
