Gemini is a racing roller coaster with a wooden structure and steel track, located at Cedar Point in Sandusky, Ohio. Built in 1978 by Arrow Dynamics and designed by Ron Toomer, it is one of the oldest roller coasters in the park. When the ride opened, it was marketed as the tallest, fastest and steepest roller coaster in the world. All three record-breaking claims were falsely made as other coasters around the world already beat Gemini. The all-steel Loch Ness Monster at Busch Gardens in Williamsburg, Virginia, opened earlier that year before Gemini and was taller but had a shorter drop. Screamin' Eagle at Six Flags St. Louis opened two years prior to Gemini and was faster at 62mph.
