Around 9 or 10 am...if a gobbler responds to you from another ridge... sometimes it will take him only about two minutes for him to run down the ridge and up your ridge too confront you. When he gets near the top of the ridge where a hunter is located. He'll sometimes hide behind a fallen log and stick his head up like a periscope to inspect the top of the ridge.
Any critter can see much further away going up the hill rather than down it.
