----------------------------Original message---------------------------- A picture I saw over the weekend reminded me of the very large US maps found at the various Sea Worlds. I've never seen one in person, but they appear to be 75 meters or so across. A few years ago, the University of Chicago's annual scavenger hunt asked participants to bring in "a map of the United States at 1:1 scale." Although an enterprising team tried to submit a diskette that would produce such a map, the judges ruled against them, as the map request was intended to be that year's impossible item. :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: Dennis McClendon, Chicago CartoGraphics [log in to unmask]
