"We stopped one night at a ranch where the people were know to me. Originally, I had come to the place riding the grub-line with a cowboy who used to work on the ranch. We had stayed, told stories, and generally enjoyed ourselves, so I though we would stop by and say hello. My father who was a veterinarian, took time out to fix the teeth on a couple of horses at the ranch, and in the evening, as we sat on the porch, I happened to comment that an uncle of mine by marriage had known Butch Cassidy.
The rancher commented that Butch had been through no long before, driving a Dodge, and had swapped a couple of tires for a saddle.
Butch was supposed to have been killed in South America but a lot of people in Utah and Wyoming knew better."
Louis L'Amour continued on about how Butch was a very nice person and well liked and had never killed anyone in a holdup.
That's what Louis L'Amour had to say about it.
