Throughout the Challenge, players are encouraged to donate to The Community Foundation Of Middle Tennessee's flood recovery efforts. Additionally, Opry sponsor Humana will donate $1 for each of the first 25,000 players. Registrants will also be entered to win a Brad Paisley-autographed Gibson guitar, $500 cash or a trip to Nashville including VIP Opry tickets. Learn more and play here.
