We've all seen them driving down the road--a rusted pickup truck belching smoke and piled 15 feet high with odd-shaped scrap wood pallets. The pallets are inevitably stacked high enough and crooked enough to resemble a Dr. Seuss illustration, and are tied down with a length of off-color rope that appears to be the same vintage as the car. The rope is never secured from the front of the truck to the rear, always side to side, as if items don't slide forwards and back when a vehicle starts and stops.
Where are these vehicles going with their cargo? And why oh why do they have to drive 80mph in the fast lane of the interstate to get there?
