Recognizing that the post-war baby boom was on the horizon, The Pretzel Company began work on establishing a line of kiddie rides and Rock Springs purchased two of them.
Pretzel started to diversify their ride lineup in the mid-'50s, advertising their "Big 3", with the Whirlo and Kiddie Circus joining the Pretzel ride. Rock Springs’ Whirlo was located at the northern end of the upper park mall at the end of a line of several other Kiddie Rides, including the Kiddie Ferris Wheel, the Kiddie Autos, Kiddie Airplanes and Kiddie Boats.Pretzel later introduced their enormously popular Thunderbird Jr. This Kiddie Turnpike ride showcased miniature electrically powered T-Birds with fiberglass bodies authentically scaled from Detroit blueprints. Rock Springs’ Turnpike Cars ran at the southern end of the upper park mall near the chainlift hill of the Cyclone Roller Coaster. (Courtesy of Richard Bowker)
