DVD_BuildItBigger[DVD: Discovery Channel – 2008 – 43 mins]. Roller coasters are pushing the limits of human endurance, and Danny Forster builds and rides the newest scream machines to uncover how. At a Virginia theme park, Danny helps daredevil iron workers risking their lives erecting the Griffon (Busch Gardens) – A 205ft tall dive coaster. He joins another team building the Renegade (Valleyfair!) – A massive wooden coaster in Minnesota. With only two months before they must be finished, the teams are forced to work through arctic winter conditions. Features optional English subtitles for the hearing impaired. ANDY SHINE SAYS: This doesn’t show Griffon and Renegade completed, and fails to report whether the teams met their deadlines(!). ANDY SHINE’S RATING: Fair / Good.
