Brown Derby Park, Thornton, Illinois (1930s-1960s)
Brown Derby "Amusement" Park was opened sometime in the 1930s by Fred Pliscott, this small amusement park had three major rides,(the Lindy Loop ride ), and five kiddie rides, including a merry-go-round. Brown Derby Park's ride and concession Manager was John Petro. The park also had ten games of chance, a penny arcade, two refreshment stands, a shooting gallery, a dance pavilion and a theater pavilion, an athletic field and a picnic area.
 Lindy Loop Ride (named for Charles Lindbergh) was a 1929 Spillman Engineering Company made ride. The canopy-topped ride featured cars resembling old-fashioned sleighs mounted on crescent-style rails. Each car held two passengers facing each other. The "restraint" consisted of a single leather strap that hooked into a metal loop at one end of the seat. As the car moved over the track (similar to a Tilt-a-Whirl with peaks and dips), the car would slide freely along those runners. A pedal at the riders’ feet engaged a clutch to flip the car upside-down.
