Folks, I see that some of you sit all day, and some don't. Some don't want to, and some want to, but just don't.
Since I've been sitting all day, I've seen more and shot more animals.
Some tips:
1-Be comfy. I take a backpack and put everything I need to sit all day. Notepad and paper. Yahtzee. Snack, with water. Binos.
2-When times get tough, tell yourself "just another 15 minutes" and keep telling yourself that.

3-Get high. You have to move sometimes. When you're higher in the tree, you get away with more movement. When I'm 22ft high, in good cover, I can do just about anything. Sit every 20 minutes.
4-A small book will work wonders. Check around after each page, if you must.
For the rest of you "all-dayers" PLEASE contribute your tips, if you wish!
