Find a boat ramp near a WMA, be there at 4:00 in the morning with your shotgun, hot coffee, buscuits, and a box or three of 3"#2s. Tell folks launching your story, and swear to never reveal where they might take you. About the 10th time you do it, somebody might take you up on it. By about the 20th, they might bring you back to the ramp, too.
J/K Just havg around and read some more. Search some posts on 'how to', etc. and you'll gain some more. Next, ask around at work, church, etc. about anyone that duck hunts. See about getting somebody to take you on some ponds or other private land shoots. Get a feel for what's involved and listen to the yarns from any that go on public ground and quiz them on what they use, how they do it, etc....but never specifically where. Bad manners. They'll offer, eventually.
I was at a ramp one time with some of my older buddies, and a teenager/young 20's hunter came up and asked us straight out where we were hunting. I told him 'on the river', hoping he'd get the hint. He didn't. He said 'Yeah, but where on the river?' My buddy promptly said, 'Preferably on top' and walked away.
That's what asking specifics will get you, on here or just about anywhere else with regards to duckhunting. Nobody can trust anyone anymore, and the ethics/common decency are missing. Show an eagerness to follow that, and folks will be glad to have you along.JMO
I'll tell anyone a whole lot more by PM than I would out here for the world to see. That doesn't mean I know all about everywhere or everything duckhunting, but I ain't liable to let on what I might, either.
Here's a thought: Let the ducks work and decoy.
