It was at a stand still like it was waiting at a stop sign!It was south of Huron, SD. Looked Like a long white brite semi (Long rectangle) crossing a 4 way on the back road moving north along the road low noise high speed. When I got to the enter section my car sputterd like it was about to run out of gas. I looked north down the road I didnt see it on the road but moving twards the sky it looked like a little dot in the distance constantly getting higher!((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information.
