I was rereading GD's Index and they had a short interview with Seth Waugh of Deutsche Bank, he's a member at Boston GC, Deepdale, Garden City, Lahinch, Lost TRee, NGLA, Old Marsh, PV, Royal Aberdeen, Seminole and Westhampton. That's a pretty good list.
Personally, I don't have 14 different logo shirts in my closet, let alone memberships.
