This Washington Post Magazine article tells the story of several professional miniature golfers who competed at the 2006 miniature golf U.S. Open.
"The U.S. Open of the ProMiniGolf Association is a two-day, nine-round competition that kicks off at the Hawaiian Rumble, which sits on Route 17, amid a string of swimwear stores, aging shopping centers, seafood restaurants and other miniature golf courses. The Hawaiian Rumble takes its name from a 40-foot, concrete volcano in the center of the course, skirted by a moat, its waters dyed the deep, alien blue of glacial ice. Every half-hour or so, the volcano quakes with artificial thunder, and a four-foot kerosene flame spurts from the caldera. On the morning of the U.S. Open, a halo of gray fog was leaking steadily from a ring of vesicles a few feet below the crater's lip, but the flame and thunder apparatus had been turned off so as not to fray the nerves of the golfers, who were already on the course, putting away with nervous intensity."
