Welcome to DHC. There's a lot of great info on here to peruse from previous years, and some nice guys that will help you out when you have questions. Best of luck to you, thanks for introducing yourself!
Have you bought a call yet? IMO there are 2 kinds of duck calls worth buying. 1 - Buck Gardner Double Nasty (Or pretty much any other $15-25 basic double reed call. These are the easiest to learn on and get good with. 2 - A single reed that works for you (I highly recommend going to game fair in August, there's a gazillion call to try out and everyone's got them "on sale". Single reeds are harder to use but I like mine when it's time to yell at em' from a ways out.
I've been hunting ducks for 6 years or so and have hunted them from every kind of boat out there (except layout). Tiny ponds, huge lakes & rivers, cornfields, beanfields, swamps & marshes can all be great locales. The best place to hunt ducks is where there are lots of ducks
The best tool for a MN duck hunter would be a solid pair of waders, other than a 12 gauge. My best advice is to not be afraid to drive a ways and hunt out of the metro area Go west far enough and the hotels are cheap and the birds are more plentiful. If you plan to stay within an 1 hour of the cities, plan on having lots of company on the water. There are a lot of nice guys you'll run into, but there are plenty of jerks too and the convenient and or consistently good spots near the metro will be camped out for most early season weekends.
