The original Home on The Range cabin still stands and can be visited on the original site where the song was written. It is located in Smith County Kansas on State Highway number 8, 8 miles from the Nebraska State Line.
Here's a summary of the movie: The movie is about how the Kansas state song "Home on the Range" came to be such a well-known piece of music. Buck Taylor plays Trube Reese, the man who discovered Brewster Higley's poem in 1875 and who told the prairie doctor it might make a good song.
