Sorry, but from your posting stating you had a new coach and trying to figure out what you were doing for the week, I made the erroneous assumption that this was your first visit. But no matter how many visits you have under your belt, you never run out of things to do or see at the OBX. It took me 40 years before I saw The Lost Colony
play that's been performed for over 75 years every summer on Manteo Island.
My first visit to the OBX was in 1961. My father had a huge wall tent and our family of five camped at the Cape Campground near Cape Hatteras. Although the 1959 Chevy Biscayne we traveled in had a cavernous trunk, we still needed roof racks and a box (which my father built) to hold all the sleeping bags and lighter items.
Back then, the only national commercial chain-type businesses on the OBX that I can recall was a KFC at Whalebone Junction and a Ben Franklin 5&10 in downtown Manteo. Bypass US 158 was a simple two lane road and the Bonner Bridge to Hatteras Island didn't exist- you crossed Oregon Inlet via ferry.
Enjoy your stay.
