If you are looking for a great theme for your story, there you go.
Or any story, for that matter…
Take Larry McMurtry’s advice: Death and rebirth.
He has sold more books that you could, most likely, ever dream of.
Of course, you could transfer this Texas theme to other areas.
Exodus, in my view, makes a great theme: the dying of the old, rural, agrarian culture, which was the only culture Texas really had until, in the Forties, the cities finally began to fill out.
