Mac Henderson started out no more of a ranch owner than he did a Navy SEAL. Adrift on the post-college tide of the '70s, with no direction planned, he headed west to surf. But fate had other plans for him-beneath Montana's Big Sky. A broken starter motor during Cheyenne Frontier Days led him to witness Ama's traditional dance for her tribe. Since that moment, for twenty years, she has believed in his dream, inspired him, and given him a son (Mark Henderson). It was only when Mac retired that she found her own dream. Her reward? Finding Henderson's Ranch.
