Bowdacious makes a great point and I hope it isn' t missed. You should always stalk your stand, daylight or dark. If you booting deer out, your losing the game before you start. Yes, deer can see at night, not quite as well as they can during light hours but they can and you will spook them if your not in stealth mode. Yes, you can seem to get closer to them under darkness, like Bow mentioned, they are less wary, at least of humans....simply put they don' t encounter humans under darkness and that' s probably the simple reason you can actually get closer however, you can blow it before the hunt begins so.....stalk your stand, don' t daylight yourself in the darkness.
