The famous outlaw Butch Cassidy, whose real name was Robert LeRoy Parker, owned a ranch in Wyoming. The ranch was called the Hole-in-the-Wall, and it was located in the remote Johnson County area. The Hole-in-the-Wall was a notorious hideout for outlaws and a place where they could hide from the law.
