Getting drugs through the official checkpoints of the U.S./Mexico border can be incredibly difficult. But the massive fence along the rest of the boundary is virtually impassable by land vehicle. That’s why cunning cartel operatives developed the “ramp truck,” a special vehicle that brings an angled ramp right up to the wall so the smuggler’s vehicle can pick up speed and jump, "Dukes of Hazzard" style, right over into America. On the way back, of course, the car has no drugs so can just pass over the border unmolested. In November 2012, a smuggler’s SUV got stuck atop the fence, forcing the driver to bail out before the border patrol caught him.
