4 different scenerios

1. If I am using my camo clothes sitting next to a tree gun is in my lap - ready on me knee as I use an Ameristep foam padded knee pad to help keep the gun muzzle almost in the ready position pointing at the area I last heard that tom.
2. If he is real close and as you said open green pasture - gun is up & pointed in the last direction I heard him gobble. Why take the chance.
3. If I am sitting in one of my open ground rag blinds (those fold-up panel type)- gun is always in my lap as I know I can get away with very slow limited movement bringing the gun to my shoulder to shoot. I practice picking the gun up - move it to possibly take the shot - on all Jakes and hens who wander into my set-up. Those birds will tell you quickly if you screwed up - real quick
4. If in my turkey hut (full enclosed blind)- gun is resting on the side of the blind until the bird is in range - only thing tp keep in mind is to poke the barrel straight at the bird slowly as you poke the muzzle slightly out past the window of the blind.

I have learned the hard way very well - trust me those birds have eyes ya never thought they had! Do like you described - you are gonna be busted soon.
