funny you say that, i have also blown my grunt while deer were practically underneathe my stand and they did not pay any attention to it....they acted like they didn't even hear it. then again i have hit the 'ol grunt tube and had deer come straight in like i was reeling them in with a rod & reel. the 6 point i shot during muzzle loader season came straight to me grunting back at me. i guess it all depends on the deer's moods.
