Army Veteran Finds Healing in Yellowstone

Green Beret and Army veteran Ray Knell was a broken man with PTSD and severe anxiety when he returned home from Afghanistan. His trust in humans was gone. A friend introduced him to backcountry horsemanship, the wilderness and animal relationship gave him hope and peace of mind. To inspire others to use wilderness and horses to overcome their struggles, Knell embarked on a 1,000-mile ride along the Continental Divide.
