North Carolina recognizes VA conceal carry permits as does VA recognize NC's permit via reciprocity. Just use common sense and stay out of restaurants that sell AND serve alcohol (the grocery store does not count). Stay off educational property, local government property, look for "no firearm signs" and proceed at your own risk should you choose to enter these places, and if ever approached and questioned by an officer, the first things out of your mouth should be something to the effect of: "Officer, I have a concealed carry permit and I am carrying." When asked present that permit with your ID. And don't drink while carrying!
Other than that, you should be mostly fine.
