There's the AIG golf course in New York that's been in the papers recently. Named "Morefar," it was built by old man Starr sometime in the 1940's as an exclusive club for top AIG performers and some of their select guests. The course's design has been maligned, but I don't know anyone who's even seen pictures of it. Supposedly, the golf course has bronze sculptures in and around it (some of which may even be in play).
One of my favorites is the putting green built behind one of the private residences at Pine Valley. I can't remember exactly where the home is, but Erskine Bowles used to be one of the owners and there was a basement wall in the house that was signed by all the celebrities who had stayed there through the years. The green was maintained by the club's greens crew and, although fairly flat, seemed to be kept in the same shape as the golf course's greens.
