The only times I planned on doing all day sits where during rifle season. I shot deer both mornings, so it never materialized and I wasn't upset. The one time that I shot my biggest buck I wasn't even to where I wanted to be yet. I headed off to check out a different area, one of those "what's over the next ridge" kinda things where I had seen deer moving previously. Stopped to get my drink out of my back pack and take a leak. Heard something as I was pissing and got turned around and grabbed my gun with an 8pt walking about 80yds from me sniffing the ground not paying attention. BOOM. Dad calls and says "wtf I am not even to my blind yet!?" Lol I went back and got the truck and got him gutted and loaded up, back to camp and had breakfast made for Dad when he got back. That was my favorite "all day sit". A heated blind or pop-up where I could move a little would make it a lot more do able. Many times I have stayed out all day, but moved mid day to a different spot. IDK if I can count that.
