1996 Olympic Rhythmic Gymnast Kate Nelson Nack, representing USA Gymnastics and the Midwest Olympians and Paralympians, opened the 2012 YMCA National Championships and Summer Fest in Milwaukee (along with the Mayor) with an inspirational speech to thousands. Kate got her start in gymnastics at the “Y.” This event was also a way to celebrate Olympic Day on behalf of the U.S. Olympic Committee. The event took place the weekend of June 30-July 1.
