Well, if anyone plans to move back, expect to pay a "road use tax" to have your car registered in the state. It will run you over $500 per car unless it is a very old klunker ($500+ for 2005 Ford Sportrac). However, you can always just buy a new car once you arrive.
If you live south of I-12 or in any of the coastal parishes, don't expect to get home insurance. You get the opportunity to go through the citizen's plan and pay $4000+ a year just to insure your home.
They have really rolled out the red carpet and welcome signs for people who want to relocate here.
