Faced with a devastating injury that resulted in the amputation of his left leg, snowmobile racer Mike Schultz was at a crossroads in his life. He was an able-bodied competitor in 2008, but was thrown off his machine, leaving his leg grossly hyper extended. Schultz, who was known as "Monster Mike," thought his athletic career was over. But the thrill of racing and desire to compete again led the then 27-year-old to his garage, where he worked for weeks to build his own prosthetic leg. Schultz brought his competitive spirit and determination with him.
