The only thing you need to OC in NC is to be able to legally own the firearm you are carrying. I have not had any problems OC'ing in Hickory. Don't get to do it as often as I would like. You don't see it much here. You may get a few questions about it, most folks don't realize it's legal. The CCP would be a plus in case you are asked to CC it by someone. Just be aware of where you cannot carry. State, city, and county property. Most of the places you can't CC you can't OC either. And the no weapons signs do carry legal weight here. I have seen everything from no CC, to no weapons period, even one that seemed to allow CC but not OC. Go figure. Hope it's uneventful for you up here.
