Rusty,
Are the turkeys roosting close to where you are setting up? If they know where you are they probably will change their route. If they don't know you are there and you always see them in a particular spot are you calling to much or to loud? You could always try not calling at all if they are always there.
As far as decoys go, you have to try to figure out what the turkeys like at that particular time. I have set out 2 hens and a jake and it will work sometimes it won't, toms will only come in so far and go the other way. Then i will just use one or two hens most of the time just one without that jake, you just have to try different things
