I remember watching an old video by Roger Raglin and he specifically stated that mid-day on public land it a big time to be in the woods because others are moving to their trucks for lunch and in that time, they are pushing deer around whether they know it or not. He goes on to say that you should pack a lunch in your backpack so that you can be in the woods longer while others are leaving. I hunt all day from sun up to sun down, it has to be pretty crappy weather to get me out of my stand.
