Augusta National is sometimes likened to Oz. For one thing, it’s a Technicolor fantasyland embedded in an otherwise ordinary tract of American sprawl. Washington Road, the main approach to the club, is a forlorn strip of Waffle Houses, pool-supply stores, and cheap-except-during-the-Masters hotels. In the Hooters parking lot during tournament week, fans line up for selfies with John Daly, the dissolute pro and avatar of mid-round cigarettes and booze. But step through the club’s metal detectors and badge scanners, and you enter a lush, high-rent realm, where you are not allowed to run, talk loudly, or cheer a player’s mistakes. Order is maintained by security guards, who for decades were provided by the Pinkerton detective agency. (Though Pinkerton was acquired by a Swedish company called Securitas, in 1999, many patrons still refer to the guards as Pinkertons.) In 2012, a fan who stole onto a fairway to take a cup of bunker sand was thrown in jail.
