RE: What to do in stand?
I read a book, or cabelas/BPS magazines. I'll even take manufacturers magazines with me to learn about new products/technology. I look up and around extremely often, and I can still hear things coming.
I don't go hunting just to kill deer though. I enjoy being in the woods, but I have a very short attention span. If I get to shoot a deer that's a bonus. I enjoy shooting my bow and guns with my friends just for the camaraderie.
I don't believe the books/magazines hurt my chances of taking a deer either. I'll see plenty of them, and I'm able to shoot as many as wish.
Sometimes I just sit and enjoy looking at the surroundings too just for the quiet and time to think.
Good luck finding something to help you pass the time.
