I don't spend much time thinking about anything other than about the animal I am hunting while on a stand or in a blind. I do a lot of visualizing, i.e. playing out the different scenarios that could possibly unfold and how I would react to each... I try to listen and be intune with my surroundings. I usually have my bow in my hand or lap the entire time.. I dont know about anyone else but I dont get away with much movement, especially when I am hunting off the ground...
Hunting has always been my escape from thinking about the everyday life....I get out in the woods and pretty much temporarily forget about all else..
