When the woods are dry and noisy, break up your steps and try to sound like a squirrel in the leaves. You can walk right up on them sometimes, noise and all. Also, using a turkey call can fool deer into thinking the noise is from one of them.
After taking a rest break and sitting for a while, take three steps and look back. Eventually you'll see your binoculars, cushion, calls, gloves, or something else you've left behind.
If you spook deer that haven't smelled you, sit down immediately and wait. Some deer will come back to see what made the noise that spooked them.
