ballroom. By the end of the 1940s, Robert Freed had fully opened Lagoon to the black community, and further extended this policy to the Terrace Ballroom (formerly the Rainbow Gardens) in Salt Lake City. The Freed family made several improvements, including the installation of new dressing rooms and a general overhaul of the swimming pool in 1949, a rebuilt fun house and the introduction of the "Dodgem Cars" and the "Lakeshore Express" miniature diesel train in 1951, and a new Ferris wheel in 1953. In November 1953, a fire damaged much of the park, including the fun house, dance pavilion, and the front portion of the roller coaster. It was quickly rebuilt to open for the next season and began to surpass the popularity of its main rival, Saltair. Many rides were restored, rebuilt, or replaced, and a few new rides were added. In 1956, Mother Gooseland, Lagoon's first themed area, was opened between the Midway and the swimming pool. It featured rides only for children. From the mid-1950s into the 1960s Lagoon made many improvements. A showboat was added to the lake, and a new fun house was built, which featured such attractions as a multi-lane giant slide; mazes, mirrors, obstacle courses, and mystery rooms; a large turntable which flung its riders off at great velocity; revolving barrels; and the ubiquitous jets of air – activated by a human operator – which startled those who were unfortunate enough to stand over them. There was also a mini-car ride added in 1960, followed by the "Space Scrambler", spook house, I.Q. Zoo, and shooting gallery in 1961. The first Wild Mouse ride came in 1965. On the Midway, musical groups including the Beach Boys, the Rolling Stones, the Kingston Trio, and Johnny Cash drew the crowds to the bandstand. The Beach Boys made mention of the park in the song "Salt Lake City" on their 1965 album Summer Days (And Summer Nights!!). The Rolling Stones concert at Lagoon was in July 1966. The narrow-gauge Animaland Train began circling Lagoon Lake in 1967. In 1975, authentic Crown Metal Products-built 4-4-0 steam locomotives were put into operation around the lake and the name was changed to the Wild Kingdom Train. 1970–1997 The turn-of-the-century-style Opera House Square opened in 1968 and showcased melodramas, musicals, and silent movies. In 1976, Lagoon expanded east by purchasing Pioneer Village, an old west town complete with several historic
