In NC, the "ban" on CC must be clearly posted. (I DO see a sign here and there so stating.)
On the other hand, since the weapon is concealed and most areas haven't gotten to the level of TSA screening (yet), who is to know? BUT..... if you happen to get caught out.... it is a violation of the Law and you can lose your permit. (Next question.... is it worth it?)
Ya pays your money and takes your chances!
