I like this thread, and though I've played the course a few times, I'm not going to offer many opinions here. I've very curious what others have to say.
As far as a unique contribution to golf, consider that the "dune" holes at Friar's Head are actually moraine holes, and that Friar's Head may be unique among great courses because it is right on the Harbor Hill Moraine, which defines the northern edge of the island.
Mike Sweeney: Because of the sensitive nature of the moraine, I doubt a finishing hole along the cliffs would be allowed.
Bstark: Take a shot at it, if you don't mind. What do you find about Friar's Head to be uniquely challenging and strategic?
An undeniably great asset of the course is its walkability. Great walk, great park. I like the course and place a lot, but I need to hear the argument for its strategic excellence.
