Bobby Benson was a young orphan who inherited the H-Bar-O Ranch (later named the B-Bar-B Cattlespread) in Texas. Though not much more than a child, he took the responsibility of running the ranch himself. His friends included the ranch foreman (and Bobby's legal guardian), Tex Mason, an old handyman named Windy Wales, a Native American named Harka, a young girl named Polly Armstead, a Chinese cook named Wong Lee, and others named Sunny Jim and Diogenes Dodwaddle. He rode rode on a wild and extremely fast Golden Palamino that he called Amigo. The name Amigo came from the fact that their relationship was based on a loyal friendship rather than conditioning.
