This curling stone belonged to 75-year-old curler Rudy Senich, of Duluth, Minn., and was used in the Winter Olympics in Nagano, Japan in 1998. According to Senich's curling club rulebook, "Curling is a game of skill and traditions . . . Curlers play to win, but never to humble their opponents. A true curler would prefer to lose, rather than to win unfairly!"
