Iowa spans 16 intersection locations where the earth's lines of latitude and longitude in whole number degrees cross the state. So what you say? Well being partial to the 42nd north parallel, the unique diversity of each intersection demonstrates how different each spot is and to what efforts people will go to document all 1,100 locations in the United States. Apparently you are never more than 49 miles way from one of these confluences. Get your GPS receiver fired up and experience the crossing of the lines nearest you. Know that.
