 The Butterfield Overland Mail route passed near Rosston, operating between Gainesville in Cooke County and Jacksboro in Jack County, Texas.Rosston, like many other small Texas towns, was bypassed by railway lines and slipped into relative obscurity in the 20th Century.But one local claim to fame is that notorious outlaw Sam Bass used Rosston as a hideout, and the town celebrates Sam Bass Day every year on the third Saturday in July.
