Keep experimenting with different calls and eventually you will find something that peaks their interest.
True, but I have to conciously and continuously keep my self in check so as to not call and change calls too frequently.
It may sound odd, but after a dry spell and not wanting to dish out more $$ for yet more calls I whipped out a turkey call and used it as I normally would for turkey and actually brought in two adults and a youngster in one evening. I was set up between CRP and a cut wheat field. Never hunted turkey in an area like that, but it did bring in the song dogs.
