Two-time Olympic medalist Rulon Gardner will be honored with a parade in his hometown of Afton, Wyo. on Thursday, Sept. 9.    Gardner is the second U.S. Greco-Roman wrestler to win two Olympic medals after he captured a bronze at the Olympic Games in Athens, Greece on August 25.    In 2000, Gardner shocked the world by defeating Alexander Kareline of Russia, previously unbeaten in 14 years of competition, to become only the third American Greco-Roman wrestler to win an Olympic gold.    On Thursday, Gardner's hometown of Afton will celebrate his career, and his retirement from the sport of amateur wrestling, with a parade that will take him through the entire town, including Star Valley High School, where Gardner attended high school.    "It's very special that Afton would do this for me again," Gardner stated. "I have been able to succeed on the mat because of the things I have learned throughout my life, and that started right here in Afton."    In 2002, Gardner was stranded overnight in freezing temperatures in the Wyoming wilderness. He suffered severe frostbite, and as a result, lost one toe.    Against the odds, Gardner returned to the mat in October, 2002. He placed 10th at the 2003 World Championships and earned a spot on the 2004 U.S. Olympic Team by defeating 2002 World champion Dremiel Byers at the U.S. Olympic Team Trials.    Gardner will fulfill some media opportunities in the morning, and the parade will begin at 3:00 p.m. (Mountain Standard Time)
