In 1962, Mapmaker C.S. Hammond & Co. asked Golf Digest for a list of the country’s best courses for its cartographers to chart, but editors thought such a list was too subjective. Instead, the magazine embarked on a four-year project using USGA course ratings along with its own research to determine the country’s most difficult tracks. The first such list, America’s 200 Toughest Courses, was published in 1966. In 1975, the list became America's 100 Greatest Golf Courses, and it's been the definitive ranking of golf courses since. In this episode of Local Knowledge, Alex Myers explores the process and criteria that go into constructing the list, how it's evolved over the last half-century, and why criticism from pundits and everyday golfers is still unavoidable.
