since you are heading for lajune head for the outer banks by way of the ferry from Cedar Island to Occracoke - and be sure to stop at Howards Pub (great food - neat spot) also in occraoke is a graveyard that holds several British sailors killed during WWII and is official British soil - be aware that this is a 2.5 hour ferry ride and then another couple hours on up to Nags Head but the scenry is fantastic - you will pass several light houses and beautiful beaches and fasinating places where the ocean has washed across these HUGE dunes and over the road during the winter - a day well spent
Below are a couple links for sight seeing you may find helpful - enjoy!
