NGLA ok; Hamptons not nearly as damaged this time as Rockaways and Long Beach Island near NYC.
Also, the real major damage was caused by the tidal surge. National has a few holes where the greens were vulnerable (i.e. #'s 14 and 17) on Bull's Head Bay, but the course is, otherwise, elevated and/or not close to the water.
Maidstone, on the other hand, has several holes right on the beach and is rightfully considered an oceanside course. If all they lost were a few tee boxes next to the sea wall, that says volumes about how being 100 miles to the east of JFK Airport was far preferable. During the famous 1938 hurricane, the opposite was true.
