I'm from Jacksonville area, best place for a baot that size here isn't the best place for hunting, especially mallards.
The Connecticut river is your best bet, almost any backwater is as good as another, there is a very good duck population, I'd recommend going over to fish it a few times to learn the river and some spots, then maybe put a blind out first sat. in sept. a blind ensures you might have a spot to hunt from come opening day, there are many more hunters here than there are places to go. esp. for waterfowl and upland birds. gets crowded fast, but still beats the couch.
good luck and drop us a line as you get closer to coming up.
