Dirty Rotten Survival

Dirty Rotten Survival is an outdoor adventure trek seasoned with a dash of grit, "man-genuity," and a whole lot of MacGyver'ing. National Geographic Channel challenged a survival savant, an engineer-inventor and a construction guru to hit the road and test their mettle by competing in location-inspired outdoor challenges across several states using a different, limited set of tools in each episode.
