Had to look twice at the picture. Single digit temps kept me in. Must be getting old as I remember son and I going to Topeka KS one year for New Years Day fly in. We had to shovel snow off the circle for take off pad. Jim Lee doing inverted laps and throwing snow up on other side of circle. I think it was two or three inches between prop marks in the snow. Also the other guys must be getting there as there used to be over a dozen of us out.
