Paul, French is not a foreign language in Louisiana although it seems LA is a foreign country in the US, perhaps as German used to be in PA. Laissez le bon temps rouler is our state motto and it just means "let the good times roll."
While working at a local sporting goods store many years ago, I sold a gun to a Cajun, a Frenchman that is, from Avoyelles Parish. We have parishes instead of counties, by the way. When he came to the question about being an illegal alien, he answered "yes." He was probably just a dumbass but he might have thought he was from a foreign country.
