This aint rocket science kid. Just get out there and scout the waterways. Ducks are everywhere. Look for marshes and swamps with standing timber. Rivers, farm ponds.
I think you really need to get yourself a copy of Realtree's Fall'n Skies DVD with Jeff Foiles for starters to get your blood pumped up. Then go out and get some Duck Commander DVD's as they get more technical on the aspect of duck hunting along with things to do in the off season.
