windsled
n.— «For residents of this remote village on an ice-locked island off the tip of mainland Wisconsin, the gliding boatmobile, known here as a windsled, is a kind of school bus.…The 9,000-pound vehicle, propelled by its twin fans and steered by a driver much the way a regular bus would be, is heated and has padded benches with room for about 20 students.» —“Across the Bay, on a School Bus Wearing Skis” by Susan Saulny in La Pointe, Wisconsin New York Times Feb. 22, 2008.
