Look for rubs and droppings below trees to determine which yield the most sought-after acorns. But don't set up amid the oaks. You're apt to alarm deer when you approach before dawn, and in the evening, does and fawns arrive before any mature bucks, bringing with them plenty of eyes and noses to bust you with. Instead, look for travel lanes and funnels leading from the oaks, and set up a stand or ground blind downwind of a promising route to intercept deer moving to and from the food source. Here, you're much less likely to spook deer.
