Drop me a PM when you get settled....... I live in Mandeville (5 miles south of Covington).
Fresh Water Fishing is good!
Salt water fishing is AWESOME!
You have several NRA's and WMA's to duck hunt within 75 miles from you including Big Branch NRA, Manchac WMA, Pearl River WMA, Salvador WMA, Biloxi WMA, etc...
Here is a link to the LDWF website to get you started:

I also recommend you subscribe to the Louisiana Sportsman Magazine. There are a ton of articles in there that will point you in the right direction of where you can hunt and fish.
They have a website and forum too,
