Roller Coaster Socks
Description: The EXT was located at Worlds of Fun in Kansas City, MO. In 1983, the Screamroller was converted to the world's first stand-up roller coaster and renamed the EXT - Extreme Roller. Due to the additional stress placed on the track by the stand-up cars, it was converted back to a sit down coaster the following season in 1984, but still retained the name EXT. It remained in this configuration until it was removed in 1988 to make way for the Timber Wolf.
Description: King Cobra was a stand-up roller coaster located at Kings Island in Mason, Ohio. Other stand-up roller coasters that preceded King Cobra were sit-down models later modified to accommodate stand-up trains, so King Cobra was the first in the world to be designed from the ground up as a stand-up roller coaster. After the coaster's Japanese manufacturer, TOGO, went out of business in 2001, parts for the ride became more expensive and harder to find, so following the 2001 season, King Cobra was dismantled and put it up for sale. When the ride didn't sell, the track was scrapped and the train's common components were used as spare parts for other rides.
