The best course I have played is Southern Hills Country Club in Tulsa. It is a world class layout that has hosted a US Open, several PGA Championships, a couple of Tour Championships and a US Amateur Championship. I served as a marshall for several of those tournaments. I live only two blocks from it (at least for now, until we move to TV later this year). Also played TPC Sawgrass a few years ago. Hope to do that again when I become a Florida resident. Another neat course I played a few years ago is the Boone Valley Golf Club just outside St. Louis, MO.
