Everytime I'm in the October woods, I'm looking for dropping acorns just like the deer are. Spot an oak tree, look under it for the brown, or green, nuggets laying on the forest floor. But not only that, there needs to be some indication that the deer have found them also. Usually they do, and there will be rustled leaves, droppings, tracks, and often a few rubs around. That's the sign we're looking for and it usually causes me to start looking around for the best place to put a tree stand.
