Frontier City

Oklahoma City, Oklahoma

Frontier City started in 1958 as a Western section of the Oklahoma State Fairgrounds, but it soon expanded and moved to its present location. The park was owned and operated by Premier Parks, and Premier's corporate offices were located on a corner of Frontier City's property. Premier Parks purchased Six Flags Theme Parks, Inc. from Time Warner in 1998, and the Six Flags name was added to most of Premier's parks such as Elitch Gardens, Kentucky Kingdom, and Darien Lake, but the Six Flags branding never came to Frontier City. Premier Parks changed its name to Six Flags Theme Parks in 2000. In early 2006, Six Flags announced the sale of several properties, including Frontier City. It also announced that its corporate offices were moving from Oklahoma City to New York, NY. In January 2007, CNL Lifestyle Properties purchased Frontier City and five other parks.

A few coasters have left Frontier City:

Excalibur sat here in pieces from 2000 until 2005, but was never reassembled. It operated at Six Flags AstroWorld from 1972 until 1998, and the plan was to have it open in Oklahoma, but it was damaged during removal and it was ultimately determined to be too costly to fix and rebuild.
Mad Mouse was a Herschell Wild Mouse model and ran for a few years in the late 1950s and early 1960s.
Nightmare Mine, which was also called Orange Blossom Special and Screamer was a S.D.C. Galaxi coaster that operated from 1980 to about 1999. The ride was originally outdoors, but it was enclosed around 1989. For many years in the early 2000's, the scrapped parts of the ride were sitting in a field just outside of Frontier City.
Nightmare Mine (see pictures below for more details) was a replacement for the original ride. In 1999, another Galaxi coaster, this one built in the 1970's, was moved from Fun Junction in Colorado to the park. It was Standing But Not Operating for many years and most of the coaster now lies in pieces in a nearby field.
Wild Kitty (1991-2012) was a Little Dipper built by Allan Herschell. It was replaced by the Wild Kitty coaster pictured below.
