Hey Turkeyhunter1,personally I don't feel like it is wise to play with turkeys before season.I usually like to let turkeys gobble on their own in the mornings anyways,and before season.That way he has no clue at all when he does hear me.
If you do call to a tom too much before season it may hurt you down the long road.I don't think locator calls do that much damage to your chances though.
On Ft.Stewart where I do most of my turkey hunting it is against the law to have a turkey call of any kind in your posession unless it is during turkey season.That means if it is in your truck you are in trouble,not exactly that you have been caught with it in the woods(but that is a ticket too).
Do I agree with that?Yes I do.I wish all public land was that way.There are too many nasty,and greedy people in the world,and if you allow them to tote calls,alot of them will go ahead and poach.That's just like leaving an ATM open.
