Book excerpt: The heritage of East Texas partakes in the same degree of unexpected turns and hidden depths as its backroads and bayous. One line of inquiry meanders into another. Start out searching for La Salle's grave and end up chasing Spanish gold in Upshur County. From Sam Houston's Bible to the Longview nightclub that hosted both Frank Sinatra and Elvis Presley, one tale follows another and introduces a cast of characters that includes Candace and Peter Ellis Bean, Old Rip, Jack Lummus and Vernon Wayne Howell. Part the Pine Curtain with Tex Midkiff for a history as heated as the La Grange Chicken Ranch's parlor and irresistible as a batch of Golden sweet potatoes.
