on the way up to the cabin i usually stop somewhere and buy a whole bunch of goodies to bring with me. i mean if you are gonna be hunting it is something to enjoy so i buy chocolate, beef jerky and well anything that fancies my hunger at the time and i just unwrap them and put them into a ziplock bag so i dont have to worry about the wrappers or littering and there is less noise that unwrapping all of them. so all i have to say is DIG IN lol
one more thing is make sure you pack lots of water or drinks
because sitting in a stand all day wears you out and you dont wanna get dehydrated...
