AU PAYS DE DIEU
Traduit de l'américain par Bernard Cohen

In American English "God's Country" is a general term of approval. Seventy years ago, Jacques Barzun wrote the book God's Country and Mine: A Declaration of Love Spiced with a Few Harsh Words. Douglas Kennedy, to judge from the back cover of the book, refers to the Bible Belt.
