Ext Merch
Main Tag:
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.
