I do about as zubba says. I go out about two weeks prior as if it were a hunting day. Wear all the camo you would as if you were hunting, go out at daybreak, and find out where they are roosting. If you dont hear them the first day you go out, move locations and try again. When you find the birds, try to find exactly where they are roosting, even if it means coming in the next day and getting in closer. When you find exactly where he/they are at, stay until flydown and figure out which way they go. (You may want to observe which way they go on a few days to see if they consistently go in a certain direction.)

Once you have figured out where they roost and which way they go after flydown, you now can determine how you will set up on the birds. Since you know where they sleep, then where they go, all you need to do is set-up between those two areas. So set-up 100 yards or so, from their roost,in the direction the birds consistently head toward after flydown, and if you do, you better get the grill ready, because this story ends with a dead bird.
