Little packs of salted peanuts or trail mix are waterproof, compact and will keep you from getting hungry on stand. Cheese and crackers are great. Jerky to kill time chewing. Hot drinks are great if a thermos isn't too bulky, but coffee has a strong smell. Three musketeers and Reeces to keep your sugar up. But for an evening or morning hunt I like being a minimalist and traveling light, eat after you get done field dressing your deer.
