converted for use as multi-purpose stadiums. Although a baseball-only facility, its design took several stylistic cues from the multi-purpose stadiums of the day, plus the Googie style that was more prevalent in the decades prior. The main stadium itself is primarily concrete, with a smooth, uncovered concrete facade. The stands wrap around the infield and end at the foul poles, with smaller bleacher sections (or "outfield plazas," as the Royals call them) in the outfield. In their book, The Ultimate Baseball Road Trip, Josh Pahigian and Kevin O'Connell wrote that it is essentially one-third of a cookie-cutter stadium, containing only the seats in a cookie-cutter stadium that provide the best views for baseball. The upper deck is quite steep, though not as high as other parks built during this time. Many minor-league stadiums built in the 1980s and early 1990s, as well as Guaranteed Rate Field in Chicago, employ a similar design. The park's best-known feature is the fountain and waterfall display (known as the Water Spectacular) behind the right-field fence. At , it is the largest privately funded fountain in the world. The fountains are on display before and after the game and between innings, while the waterfalls are constantly flowing. When the stadium was originally built, Kansas City was the westernmost major league city other than those along the Pacific Coast (1,600 mi. [2,600 km] away), which was a major reason why the Royals initially decided to use a faster-draining AstroTurf surface. The Royals' home territory included a large swath of the Great Plains and Rockies, and Kauffman didn't want fans who drove many hundreds of miles to go home without seeing the game completed. The Truman Sports Complex's legendary groundskeeper, George Toma, best known as the head groundskeeper for every Super Bowl, thus had the job of maintaining two carpets for most of his career. He also maintained the surface at Arrowhead Stadium, which had AstroTurf from 1972 through 1993. However, Toma has said that artificial turf requires a good deal of maintenance as well; his crews were able to keep Royals Stadium's original carpet for two decades, somewhat longer than the typical lifetime for outdoor artificial turf. This is also due to the fact that Kauffman Stadium has never hosted a football game, and has no movable seating, thus avoiding the wear and tear typical of cookie-cutter stadiums. The stadium's AstroTurf was replaced by grass for
