From the third week of Oct. thru the second week of Nov, I'll stay out all day. Sometimes it gets the best of me and I'll switch stands, but I will try and sit all day. I have killed the majority of my MATURE bucks at this time of year, between 11 and 3. Mostly around 2-3 p.m. for some reason. I couldn't tell you about mid-day big buck movement the rest of the season as I don't sit all day during those times. It seems the older I get, the harder it gets to sit all day, partially due to discomfort, but mostly because I sit there and think of all the honey-do's and things I should be doing. Nonetheless, I enjoy my all-day sits.
