John J. McGuire & H. Beam Piper 
Lone Star Planet [PDF ebook] 

Texans have long been known as ornery pioneers who like to have plenty of space to themselves. In Lone Star Planet, science fiction luminary H. Beam Piper posits a future where Texans have colonized a planet (known as New Texas) and pass their days wrangling giant herds of dinosaurs. It’s a rollicking read for fans who like a heaping helping of satire with their SF.
