It would be a pretty big change. Definitely visit before doing anything drastic.
Houma is close to Thibodaux. It's bigger and probably more livable overall.
I totally agree with you there, I hope to visit out there in a few months, luckily I am very used to the small town living (as long as I can find a "watering hole" close by) its my wife im more concerned about although she is feed up with the Big city life herself.
