Cowboy poetry in Montana
"...[T]he cowboys of Lewistown, Montana? They’re a model to follow. They have a culture, a place all their own, and they are striving to preserve it. To that end, they gather once a year to celebrate their shared past. They visit with old friends, and they welcome new ones. In their song, they remember what their lives used to be like. They keep a record of roping cattle, and of looking at the skies for direction, and of comforting each other when a cowboy falls."
