All, we're perhaps well off topic here but regarding ORV beach access areas and closed areas in CHNS, there are always areas which are closed to vehicles. In fact, much more of the beach is closed to vehicles in summer than winter so no reason to avoid visiting us in summer. See below.

In addition to this there are local closures for sea turtle nests and birds nest sites that come and go.
Living in Hatteras Village and not being a beach driver (not only do I not like sitting next to cars on the beach but driving on the beach destroys vehicles in short order), we usually go to the beach access point opposite the maritime museum. From there east is restricted in summer.
If you're at the Frisco CHNS campground, the beach directly in front of you is open to vehicles all year but just to the west is closed to vehicles in the summer. Or you can park at the Frisco parking lot and go east from there.
And, if you want as much privacy as possible, if you park in the airstrip parking lot and walk across the end of the runway (do check for aircraft first please, you usually won't hear them when landing) there is a path that leads to probably the least busy beach in the area.
Hope y'all come and enjoy your stay but keep an eye on the tropical Atlantic, its really heating up now (pun intended).
