- Six Flags Great America
- Columbia Carousel
Columbia Carousel (known as Carousel Columbia at California's Great America) is a pair of double-decker carousels at Six Flags Great America and California's Great America. Both parks were originally built by the Marriott hotel chain as sister properties but they were later sold off and are presently owned by Six Flags and Cedar Fair, respectively. To this date, Carousel Columbia (the California counterpart) is the world's tallest carousel.
