Shut up and see game. Pros move quietly. Modern life doesn't lend itself to silent walking. Don't rub up against brush. And take the squeaks and clangs out of your pack and clothing.
Pros walk with their heads up.
No one wants to trip and fall, which is why we have a tendency to hike with our heads down. And yet, I've never shot a deer off the top of my boots. Pros aren't afraid of the dark. Most deer movement occurs during the first hour after dawn and before dark. To take advantage of this, you'll have to hike to and from your stand by flashlight.
