RE: how to scout?
As I said, someway - try to figure out where they are when you hear them gobble. If it is form the same palce at the same time on several days - get there before they do.
You are going to have to figure out a way to listen for them before sunrise, sdo you know exAdclty whith trees theye are roosting in. Then figure out a way to find out where they like to go to eat and strut in the morning (they often go to open fields, with low cover). Then get between where they roost, and where they go to eat, and setup there.
Turkey hunting often involves a lot of scouting ...
God bless,
