You don't have to travel to Nevada or England to experience the mysterious phenomenon of extraterrestrial life forms. Much like that of the famed Area 51, strange lights have illuminated the skies above a 20 acre section of cropland right here in South Dakota. This section of land has come to be known as "Area 81", located in the heart of a geographical triangle with points of Sioux Falls, Yankton and Mitchell. In addition to the cosmic illumination, bewildering patterns of intricate paths and shapes have been mapped in the corn field directly below the lights.
