google maps.
Drive time - unknown, might be just at the edge of your feasibility range K_os.
I'm liking the idea.
I don't know the most North-ward beach that is driveable /campable in NC. - but I think it's Nags head.
which is 5 hours from me (No-Va (DC beltway)) but further for those north of me (MD). Assateague appears to be the most friendly of the accessable areas. (Camping is not anywhere on the beach though).
I'll keep this thread open for suggestions on times / locations up to June 16th, then I'll make plans for my trip.
