I actually played in the Dunhill about ten years ago, after we finished Sebonack. (The chairman of Dunhill, Johan Rupert, was the first founding member of Sebonack.). It was all a bit surreal, hanging out with the likes of Herb Kohler, Boris Becker, and Michael Douglas (and his wife!). Two or three of my clients play in it every year, and think it's a blast. I'm sure the AT&T is also first class, but for a boy who caddied at St Andrews 25 years earlier, the Dunhill was hard to beat.
