I agree with this, but I do feel you can do things to swing the odds in your favor. By baiting, using calls, urine attraction, mineral blocks can keep deer in the area. However, it does no good to have any of these things if you are not in their territory, or your scent gives you away.

If you scout hard, stay scent free, use attractants, practice your shot and keep out of sight you have a great chance of taking a deer.
