What the land had, in spades, was immense tumbling dunes, some 50 feet high or more. And the potential, once the nonnative trees were cleared, of becoming home to not just one but four or five spectacular courses. The firm, sandy fairways, long open views, and exposure to strong winds would evoke the famous links of Scotland and Ireland and pay direct homage to the less well-known but well-loved “heathland” courses outside London. Mr. Keiser bought 1,700 acres from a tree plantation owner. He commissioned the golf design team of Bill Coore and Ben Crenshaw, a former touring pro, to create a new course, to be known as Sand Valley. It opened last week.
