I agree you can pick a good spot from topo maps, but it will be determined by wind direction. I would uggest wait and see what the wind is doing and then decide. One day deer might be in one spot and the next day they be 50 yards from that spot. Pick a spot and have patience. If you have stands to hang, then hang one in each spot and see what the wind is doing. If you have a climber, then hunt the spot determined by wind direction. Yes you can narrow spots down from topo maps, but it will come down to WIND!!
