Patience, Patience, Patience!
IF oyu are seeing fresh overturned leaves, that tells me you are spooking them going in. How far from your stand is the car being parked?
If less than 1/2 mile I suggest you work from the minute you arive to the parking spot at making NO noise what so ever. Don't slam the door or trunk. Shut them as softly as possible. Still hunt your way to the stand taking a step or two and spending 3 to 4 minutes looking around with binoculers. Look as far as you can all around you looking not for the whole deer but a shadow or flicker that dosn't look right. Also after you have entered the woods from your parking place let the woods settle down before you start moving toward your stand. Listen to the birds and squirrels and other woods noise. Then as you are moving to your stand try not to disturb this normal sound.
Don't keep moving the stand for the time being. If the position was picked for you, you have to trust the placement untill you see deer moving 40 yards away consistantly.
Good Luck
