"Before Iron Dragon’s 1987 debut, the Western Cruise (later known as Paddlewheel Excursions) boats circumnavigated the waters around this island. The popular boat ride’s station sat on the same part of the midway where Iron Dragon’s station rests today (In fact, observant Iron Dragon riders can still spot the docking cleats welded to the dock while climbing the stairs to the boarding station). The Monster circular ride used to call the land under Iron Dragon’s transfer track home. Monster closed on Labor Day weekend in 1986 so Iron Dragon construction could begin. Planning for Iron Dragon began in 1985, the same year the Frontier Lift cable car ride (similar to the Sky Ride found on Cedar Point’s main midway) opened for its final season."
