Martinsdale was a sheepman's town; to the west is the Smith ranch of 86,000 acres and to the east the Bair spread of 80,000 acres, two of the biggest sheep outfits in the state. Bair was one of the most successful sheep owners in the world, at one time running over 300,000 head. The Bair Family Museum gives an intimate view of one of Montana's most prosperous families.
