At my age, all of my deer hunting is done out of nice roomy box blinds, so a little aroma or wrapping paper is not a problem. For years now I have taken a small thermos of coffee if it’s cold, and always water. For snacks, I like a small can of honey roasted peanuts, beef jerky, and Little Debbie Swiss Rolls. Occasionally maybe a Snickers or some other candy. The deer don’t seem to mind.
