LAND YACHTS. How else to describe those rolling hotels called recreational vehicles, with a smaller vehicle on a drawbar trailing along as if a dinghy? Today I saw something that meets the test for "excessive." Consider a converted intercity bus (or are there now campers built on bus platforms) with a large Ford (Expedition? Stretch Explorer) in the dinghy position. A Minnesotan, highballing at 85 mph plus. (And why do Wisconsinites complain about aggressive Illinois drivers? The Minnesotans are truly nuts, even in Chicago traffic.)
