I once woke up to see a buck in the field in front of me... and shot it. I had a job working midnight shift. I had sat at the base of a tree watching a field. And the nice warm sun was shining on me, and I was so comfortable sitting there. What made me wake, I have no idea. But I opened my eyes and there was a little five pointer out in the field. So I raised the rifle to my knee, and ended my hunting that day.
