There are plenty of things to do once you get to Louisiana. Here is one:
It is a reconstruction of a Cajun plantation dating from not long after the Acadians were moved from Acadia. I think it is extremely interesting.
Also, if you go down the Mississippi on the East side down through St. Francisville, you can see many antebellum plantations. If you happen to drive down through Natchez, Mississippi there are some fine old homes there too.
Bonne chance, et soyez bienvenue a' Louisiane. Il y a beaucoup des sites Cajun et historique en Louisiane.
