There is in this country a group that is above presidents, generals, and tycoons. Many of its members, indeed, would not indulge in such mundane pursuits as politics or commerce. In its fashion, this group is not unlike the British Monarchy: it endures while prime ministers, political parties and parvenus come and go. It is the Establishment's Establishment. Popularly, it is known as the "horsey set". Their Turf is an in-depth, behind-the-scenes look at a lifestyle most will know only from the bleachers and many, many more will never know of at all. Defying the gravity of democracy, America's princely dynasties endure as do their passions for their favorite pastimes, thoroughbred horses and horse racing.
