i try to avoid hunting over food sources in the morning, particulary in the early season as if there are deer there, i may spook them and if there are not deer there when I show up I probably will not see anything. I hang back and hunt the edges of heavy thickets, the ones where the first rubs and scrapes appear. That of course means I have to have a very relyable wind, and be willing to sitthrough 2+ hrs of darkness to get in there early enough, but it worked last year
