Try getting in there in the am and making no calls or at least very few if any clucks and light purrrs. Also I'm surprised anyone is taking advantage of the eveing hunting in Pa I grew up huning in Pa and even when I travel to other states anything after about 3-4 oclock in the afternoon doesn't feel right. I think I'm just so conditioned to hunting them in the morning. I almost did it this year in Kentucky I knew of a hill side that 5-6 birds roosted on every night just couldnt bring myself to hunt spring turkeys in the eve. "nothing agaist it" just feels odd personally
