despite the nominal connection to country music, the park's theme was American music in general; there were jazz, gospel, bluegrass, pop, and rock and roll-themed attractions and shows in addition to country. Opryland's focus was more on its musical productions than its rides and other attractions, which helped attract adults as much as children, the target of other similar venues. As such, it was billed as a "showpark", instead of an "amusement park" or "theme park" in its early days. Major thrill rides at the park's opening included the Timber Topper (later renamed Rock n' Roller Coaster) roller coaster and Flume Zoom (later renamed Dulcimer Splash) log flume. In its fourth season in 1975, Opryland added the "State Fair" area on land formerly occupied by the buffalo exhibit. The expansion featured a large selection of carnival games, as well as the Wabash Cannonball (named after the famous Roy Acuff tune) roller coaster, Country Bumpkin Bump Cars, and Tennessee Waltz (a song made popular by Patti Page) swings. However, shortly before opening, the Cumberland River flooded most of the park, as deep as in some areas. The park's opening was delayed by a month, and several animals in the petting zoo died in the floodwaters. Opryland became very successful during the mid-1970s. By the 1977 season, the park was the most popular Nashville tourist attraction, drawing nearly two million guests annually, mostly from Tennessee and adjoining states. The park also drew upon the continued appeal of the Opry show to country music fans from the Southern United States and the Midwestern United States, who often brought their families for several-days' vacation in Nashville. The nearest theme parks comparable to Opryland were four to six hours away, in places such as Cincinnati (Kings Island), St. Louis (Six Flags over Mid-America), and Atlanta (Six Flags Over Georgia). Attendance continued to climb into the 1980s. Initial plans had called for a commercial corridor called Oprytown to be built on the land, but due to the overwhelming popularity of the complex in its early years, the master plan was altered to include a hotel and convention center which could house Opry and Opryland visitors on weekends, and also draw convention-related business during the week. In 1977, Opryland Hotel (now Gaylord Opryland Resort & Convention Center), a large resort-style hotel, opened next door to the park and later expanded several times to become the largest hotel
