First off, welcome to HuntingNet. A bunch of knowledgeable turkey hunters here. I only hunt public land down here in Florida. In my experience, late season public land turkey hunting can be both good and also tough. The hens have left the gobblers to tend the eggs but the gobblers have been hammered by lots of hunters. Do you have a turkey hunting mentor? A mentor can REALY reduce the learning curve. Keep practicing your calls but remember, less can be more with calling. For me, learning the woods im going to be hunting and what the birds are doing is more important.
Get out and scout.
