We arrived at our farm approximately 4am, My friend,2 sons and I were stretching outside from just arriving outside of our truck, getting ready to head to our deer stands. When three of us me and sons were looking up to see all the stars on that clear winter cold nightsky when suddenly in the tops of the empty 15 foot trees, a ball of light the size of a large grapefruit lit up the non leaved tree brances it was right above for about 30 seconds, then suddenly moved across our 40.acre field, when halfway across it blinked out suddenly same it came on.Jason
