The 15 years or so from the mid-1960s through the end of the 1970s is rightly regarded as the Golden Age of American Thoroughbred racing. Beginning with the Kentucky Derby and Preakness victories of Northern Dancer in 1964, the following decade and a half produced a steady stream American-bred horses with credentials both on the racetrack and in the breeding shed that rival or surpass the all-time greats of the Thoroughbred breed.

Airdrie Stud announced fees for its stallions for 2017, and Cairo Price, Creative Cause, and Majesticperfection top its eight-stallion roster with fees of $15,000 each.

Leading first-crop sire Union Rags will stand for the second-highest advertised fee on the Lane’s End stallion roster in 2017, rising to $50,000.
