Historical Highlights

A memorable and iconic component of World Dairy Expo is the annual theme and Showring display. 2009 embraced the legends in the dairy industry with the theme "Legendary." The Showring represented everything in a ballpark, from the infield display and dugouts to the Hall of Fame banners of previous Supreme Champions.

Harvue Roy Frosty EX97-2E is one of the few Supreme Champions that has claimed the title back-to-back, being named Supreme Champion in 2009 and 2010.  She was a three-time All-American winner, claiming this title in both 2009 and 2010, in addition to 2007 as a Senior Three-Year-Old. You can learn more about Frosty here.
