Discovery Civilization races and explores with two new series

Folks who love their power tools will get a kick out Discovery Civilization's four-parter Power Tool Racing. Common power tools (drills, skill saws and the like) get the Pimp My Ride treatment as they get souped up for drag races. The hour-long series begins on Monday, April 3 at 8 p.m. The five-part, hour-long Urban Explorers hits TV screens beginning Monday, April 17 at 9 p.m. The series follows an urban historian, a structural engineer and two pro urban climbers as they explore the history, engineering and architecture of cities such as Chicago, Detroit and Milwaukee.
