'Lone Star Planet' was originally published in 1958 as 'A Planet for Texans.'

In 1999, the novel won the Prometheus Hall of Fame Award for Best Classic SF Novel. This tongue-in-cheek tale features a planet of Texans whose dinosaur-sized cattle have to be herded with tanks. The protagonist is an insubordinate junior diplomat who is appointed as ambassador to this cantankerously independent planet.--Wikipedia.
