20 years ago today, the greatest roller coaster of all time opened at Cedar Point. Millennium Force travels at an optimal speed of 93 mph, has the best hills-to-twists ratio, and lasts the perfect amount of time: 2 minutes and 20 seconds. Its not bias, its simple roller coaster science. Pay homage to one of the worlds tallest and fastest coasters and pine for the day you hear those precious words over the loudspeakers: Riders, how was your ride?
