Millennium Force is a steel roller coaster built by Intamin at Cedar Point amusement park in Sandusky, Ohio, United States.
 It was the fourteenth roller coaster to be built at the park since Blue Streak opened in 1964.
 Upon completion in 2000, Millennium Force broke six world records and was the world's first Giga Coaster, a roller coaster that exceeds 300 ft in height and completes a full circuit.
 It was briefly the tallest and fastest in the world until Steel Dragon 2000 opened later the same year.
 The ride is also the third-longest roller coaster in North America after The Beast at Kings Island and Fury 325 at Carowinds.
 It was the first roller coaster to use a cable lift system rather than a traditional chain lift.

Corkscrew is the name of a roller coaster at Valleyfair in Shakopee, Minnesota featuring one vertical loop and two corkscrews.
 Built in 1980, Corkscrew was planned to reflect the design of its sister roller coaster Corkscrew at Cedar Point.
 It is notably one of the first roller coasters to feature a double corkscrew, as well as a vertical loop.
 The main differences that the Valleyfair model has is the addition of a finale helix and the omission of the camelback before the loop.
 Until the hypercoaster Wild Thing (the fifth highest and fastest roller coaster in the world at the time it opened in 1996), Corkscrew was the only outdoor all-steel roller coaster in Minnesota.
 Corkscrew is currently the only roller coaster at Valleyfair with inversions.
 The coaster's track was painted blue when it open in 1980 but was repainted orange and yellow in 2011.
A lift hill, or chain hill, is an upward-sloping section of track on a roller coaster on which the roller coaster train is mechanically lifted to an elevated point or peak in the track.
 Upon reaching the peak, the train is then propelled from the peak by gravity and is usually allowed to coast throughout the rest of the roller coaster ride's circuit on its own momentum, including most or all of the remaining uphill sections.
 The initial upward-sloping section of a roller coaster track is usually a lift hill, as the train typically begins a ride with little speed, though some coasters have raised stations that permit an initial drop without a lift hill.
 Although uncommon, some tracks also contain multiple lift hills.

 Cyclone held the title of world's tallest roller coaster until 1964 when it was surpassed by Montaña Rusa at La Feria Chapultepec Mágico in Mexico City, Mexico.
