This isn't an "oops" or a "don't" but several years ago, my brother and I were out bowhunting on a large track of state land. Neither of us saw any deer from our stands. We walked back to the truck for lunch and laid our bows on the hood. As we were standing behind the open doors of the rig getting our sandwiches and drinks, a nice wide 8 point comes out of nowhere with his nose to the ground heading straight for us. My brother and I both saw the buck at about the same time and he said something like "Dan! Buck!". The deer was only 15 feet from the front bumper and he lifted his head when he heard my brother speak. Had Mike not said anything to startle the buck, he may have knocked himself cold on the bumper...
