G.W. takes a turn behind the wheel as he and Lisa tackle "Dead Nun Canyon" with a load of dinosaurs too tall for the tiny tunnels. Rookies Tim and Tino challenge veteran Hugh Rowland for his self-proclaimed "King of the Road" title, and they're willing to trade words--and paint--to beat Hugh this time around.
