Jay,
Looks like you came to the right place!
Like others mentioned, watch for a DA meeting announcement, then try to make it. We'll do a lap around the room introducing everyone (real name, ifish name) and when we get to you, just stand up and say, "I'm the dude that is coming back to duck hunting and I need some pointers". After we're done, watch the other duckers flock to you in an effort to spread the virus.
As far as pointers go, I'd suggest sauvies for public hunting. As far as leases or clubs go, craig's list can be a good place, as well as the ads in the paper. I see ads every once in a while in there.
I would recommend getting a copy of this book to refresh your memory of public areas, even though it is a little dated and some info is no longer applicable:

Hope that helps some. Hope to see you at the next DA meeting.
