I have had three times on public land when working a turkey with a full set up that young punk run and gunners busted in on me and ran my tom off. They hear a tom gobble and come charging in on you, it does not seem to matter if they know you are there or not. One time one ran right between us and through my decoys. When I yelled at him, the turkeys busted and he turned and pointed his shotgun at me, that was a major mistake on his part. He now hunts with a Bear recurve and hates run and gunners.
I don't hunt public land on the weekends, but I will be going out for some more turkey abuse next week on public land, to collect some morels and ticks if nothing else. Around here towards the end of the season toms come in quicker at times, but quite often they do not talk much or at all.
