Me and my wife have shot all of our deer on the ground. My wife's thing is to stare down at her left shoe when a deer is close and not look at the deer until she shoots. The other night I called in a deer. It stopped with a large tree blocking my view of the front half. I decided that anything with that big of a butt, horns or no horns is a trophy. At 25 yards, I failed. I peeked around to see what it was. A large flat nosed doe. What she saw was one dumb ass that peeked around a tree at her. She was a smart old girl, she kept that big tree directly between me and her and simply raised her tail and walked away. Shot timing when ground hunting is critical. Sometimes slow can work better, but most of the time knowing when you have a shot that is clear and has the right angles and simply getting on with it and making the shot works best. Actually, my shot tempo with a longbow is about a smooth "one thousand one" tempo from beginning of draw to release. If a shot can be made slow it can also be made at that smooth 'onethousandone' tempo. For the most part a deer that is staring at me is not a target. A deer can pick up on the tiniest motions in a stare down. You may think that the bow is not moving, but a deer will see the tiniest movement when it is staring at you and a waving bow is a quick give away. If the thermals shift on you, you will have to shift with them. I had a small buck last year snort and get all up about something it smelled. I thought at the time it couldn't be me the wind was in my favor. After it left I lit my pipe. The smoke went up the hill away from where the deer was, then I saw it not lifting, but it turned and headed down the ravine towards where the deer was standing. Evening thermals can be tricky wandering devils.
