If I really want to get serious, I get completely off sugar and caffeine. If I do not have the patience to scan every thing with my binos, I know that I have to just sit. If there are a lot of other hunter in the woods, I go to where they never do. Areas that do not have any place to put tree stands. Then I still hunt until I find the right wind conditions, cover, and deer sign, then I stop and sit tight.
I had a lucky tree stand years back. I put it way back. I left my truck at first hunting light and I still hunted all the way to the stand. I took food with me so I could hunt later in the day. when I left it I still hunted all the way back to the truck. I got my deer every year while sneaking back and forth to that stand and never got one good chance while sitting in the stand.
