Public land is tough. the birds get call shy real easy. When you have every swinging #### in the surrounding 200 mile radius, hunting on that land, the birds get real shy, real quick. On a side note, less calling is better, from my experience. When they are roosted, at first light, I like to give a couple of clucks when I first hear them gobble, until they respond to your call. I then don't do any more calling until they hit the ground. Then I give a couple more so they know I am still there. Then the waiting game begins. Turkey hunting has to one of the most exciting experiences out there. You become the hunted. I am almost wetting myself thinking about it.
