The story of Coyote Races Buffalo is a tale told by Calvin Grinnell of the Mandan Hidatsa Arikara Nation. It was uploaded to YouTube.com on September 11, 2007. It's YouTube description labels it as "A cautionary tale from the oral tradition of the Mandan Hidatsa Arikara Nation." During an interview of Calvin Grinnell, he explained to me that the video was made in his spare time at his office in New Town, North Dakota. He made the video out of personal interested in producing a video version of the story, and also uses it to entertain his grandson. (Grinnell 2008)
