In 1958, the park opened along Route 66, now Interstate 35. It featured a haunted farm, mine train, robberies and jails. Initially, guests entered for free but paid a quarter to watch the gunfight shows. It started out as Boomtown, a replica of an Oklahoma pioneer town that was built for the state's semicentennial celebration in 1957 at the Oklahoma State Fair grounds. Jimmy Burge, leader of the committee that built it, decided to open an amusement park with the same theme. Rather than a traditional ribbon cutting, it was scheduled to have an old fashioned six shooter aimed at a piece of rope stretched across the stockade entrance. That is the same manner used today for its opening. It added spinning rides, roller coasters, and a log flume ride starting in the 1960s and 1970s.
