Drive toward Okracoke Island on 12 but don't get on the ferry, If I remember correctly, there are public access sites down there and very few people right after you cross the first bridge before Rodanthe. Also, I would think you could ride in the sound at last resort if its legal now. I do not know the riding laws out there, seems like I heard they have outlawed all JS in the surf but not sure. But, you know you can do what you want as long as you don't get caught or are willing to pay the fine.
