After hunting the archery season of early September here in B.C. I came up with a few observations of hunting whitetail deer:
as for whitetail hunting, I found that they move around in the areas that I hunt from 8am-4pm for whatever reason but the big bucks are more nocturnal. In the heat of the day I have been able to locate them bedded down around stream and creek beds in the grass, you may want to try that mid day and sit in the stand at dawn and dusk. Even early on the whitetail seem to be on a pattern so if you see them in one spot chances are they will be there again, I hope this helps. For a good article on whitetail hunting check out the link.
