RE: what to eat while hunting
Bottled Water is a must for me. I also like to bring some granola bars, and a trail mix with me.
If I am staying on stand all day like in the colder gun season, I will bring a thermos of hot beef bouillon and a few ham & cheese sandwiches, plus some oatmeal raisin or choc. chip cookies.
I try to stay away from really loud foods like chips, or smelly foods like gum, jerky, garlic laden food, etc.
I find that if I eat too much on stand, I tend to get sleepy, but the colder the weather, the more I need to eat to keep the old body furnace going.
