I would probably hang it and hunt it the same day. It will help you keep the element of surprise. Deer can smell your scent for hours after you' re gone and they may become weary. Or maybe they won' t! I' ve seen deer walk the same path that I used only slightly after I' ve set up. I guess it all depends on how much human traffic the deer are used to. Or maybe because I spray my boots and legs with scent eliminator and they don' t detect me as well. If you hunt an area where no human sets foot all year, then definitely hang it and hunt it the same day. If it' s an area where the deer may see through hikers throughout the year, then they are probably used to it anyway. In any case, good luck!!!
