howdy, what part of NC are you planning on traversing?
normal caveat - I am not an attorney nor representing myself as one.
for your reading pleasure I have attached the link to the NC Attorney General's
2013 tome on their perspective of NC Firearm laws. The honorable John Aldridge, retired Dep AG and someone who has worked within the AG working on Firearm concerns, did an excellent job compiling the document as it is written quite well and to be honest is what is presented from NC's DoJ to their unique population.
http://www.ncsheriffs.org/documents/2013 NC Firearms Laws.pdf
so instead of wading through the NC statutes, you might wish to take a gander at section III, beginning on page 11, of this document and read through it as i believe you will discern the answers to some, if not all, of your ongoing queries.
of particular interest is section III D,
Transporting weapons, beginning on page 22 as it is chock'd full of information not readily found specifically in the statutes but germane to transporting firearms within the Tarheel state. and things that you should be aware of.
holler if you have further clarifications as you have seen WW, et al., will provide guidance to the best of our abilities.
and depending on your destination within NC perhaps a bite to eat could be shared during your visit.
safe sojourn
