RE: baiting at night
I agree to work a bait properly you need time to get a pattern. Also deer will become accustom to coming when the bait is freshed, & often come around then. If you baited at night it would be counter productive, IMO. Your much better off baiting in the morning or midday to try and pattern the deer using the bait to the legal time you can hunt. Of course this is assuming the bait is placed in an area that the deer would feel safe to come out and feed in broad daylight...since you said stand I will assume your hunting the a wooded area. A good bait will have deer on it almost all day long regardless of the time of day, some deer will only come at night though but not all deer will keep the late hours.
I haven't baited for a few years now, but we would try to have them rebaited by noon and it worked fine. We often kicked deer off the bait only to have them return shortly after the scene settled. The key is pattern and keep it stocked, once she runs dry then the deer move on!
