If you're hunting a small private piece of property that really only has one spot to sit, no moving if you hear a bird off in the distance, how early before sunrise do you go in? Personally I really don't see the need of getting there any earlier than 45 min before the sun comes up. I'm only walking about 30 yards from the truck and not competing with anybody for the spot. So might as well take advantage of the sleep in time right?
