Resumen de The four corners of America
Ron Lancaster (ed. lit.), Brigitte Bentele (ed. lit.)
Madawaska, Maine, is the most northeastern town in the United States, and is one of the stops on the Four Corners Tour organized by the Southern California Motorcycling Association (photograph 1). To complete the tour, motorcyclists must visit all four corners in twenty-one days or less. They can visit the cities in any order, and they do not have to return to their starting point. Riders have to verify that they were in each location; the rules are posted at http://www.madawaskafourcorners.org/.
