Undated handout photo courtesy of the U.S. Department of Homeland Security shows an off-road go-kart. U.S. border cops in far-west Arizona have seized the go-kart and trailer packed with marijuana, in the latest bizarre attempt by Mexican smugglers to beat beefed up border security. The Border Patrol's Yuma sector said agents and officers from the Cocopah Tribal Police Department spotted the single-seater go-kart hauling a trailer through the desert near Yuma, Arizona on Tuesday night and gave chase. The driver abandoned the homemade vehicle, which was spray painted a desert beige, fitted with knobbly off-road tires, and towing a trailer packed with 217 pounds of marijuana, about 100 yards from the border, and fled back to Mexico.
