Cape Hatteras Lighthouse! This iconic light was moved I think half a mile inland on rails back in 1999 because the beach in front of it was rapidly vanishing. It was quite an operation and the whole thing went at the pace of 5 feet per minute. It went perfectly. You can still walk along the flattened ground where they laid the huge tracks from the Light to the beach.
On the way back we stopped for a sandwich at a place called Bro's. It was in fact staffed by bros, yet the food was delicious, and they had mixed sixes of cold craft beer for $10. What's not to like?
