I try to put my corn or a salt lick right where I can get a good shot. I try to make it so when the deer are coming up to it they are behind brush so I can see them but they dont see me. I also might put my pile where the deer has to stick there head behind a bush or a big stump. that leaves there body open but there head is completely covered so as to cover there eyesight. it works as long as they put there head right, but even if they dont its still the same as taking a shot on a deer just walkin.
