I'm a part of the French revival movement in South Louisiana to help preserve the culture. Most French speakers are 60+ years old, which is sad. Before about 1970, children suffered corporal punishment if they spoke French in school. Blame it on the Anglo-protestants.
There isn't much French spoken in Nouvelle Orleans anymore. Same goes for Baton Rouge. This largely happened after Reconstruction: some of the Yankee leadership who took over were just as xenophobic as Southern slave-owners. I'm not trying to defend this change in leadership having to occur, it was necessary to make sure the South didn't try to keep slavery alive. Unfortunately, nationalist leadership was much like today's conservatives in wanting the only official language of L'etats Unis to be Anglais.
South Louisiana is highly underrated though, especially the city of Baton Rouge. Weed is decriminalized, there's an incredible symphony orchestra, plenty of art museums, and damn good food. But it's much more "American" of a town than New Orleans or Acadiana.
Here's a hilarious article explaining the division between North and South Louisiana:

Anyway, laissez les bons temps rouler, vous-autres!
