I never stay up all day. Actually the only time I hunt in the middle of the afternoon depends on the lunar table. If it's a full moon, especially later in the season, I wont go out till 10 or 11 and then hunt til sundown. From my experience, where I hunt, I can't remember a morning hunt where I saw a deer from sun up til 9 in the morning. The lunar tables and the barometer also play a role in deer movement. Back to the subject, to early to hunt all day anyway...IMO.
