Man, Arch, Love "the talk".. Glad you have an interest and hope you will follow through. If you enjoy the challenge of turkey hunting, you'll love matching wits with ducks and geese!
If you have a boat and water, even YOU can become a waterfowler.... just kidding friend, that just came to me
Not knowing anything about your state and it's laws governing it's waterfowl, I suggest you get a copy of your migatory game laws, just so you will be legal. While the migartory birds are under federal guidelines, each state is a little bit different with it's laws.
If you have been fishing the lake, hopefully in the fall, you will need to "watch the ducks/geese". Be looking for what type of ducks you have ,where they like to hang out, (and why) and as you study the ducks, notice how they are sitting on the water, that's how you will be sitting you deks out ....
Also, get you a middle of the road call, if you continue with the sport, you will have a million of them... Like turkey hunting we now have lots of duck/goose hunting DVDs and tapes out. They will help you with the calling and also give you a lot of info about calls ,decoys and the like.
As far as deks, a few doz mallards and a doz floater goose decoys should get you up and running. I'd suggest e bay or "greenhead gear" Hot buys, the are a good decoy for the money.
Good Luck and I'll be willing to help any way I can, so much so, COME ON OVER TO VA, We 'll do a hunt
