A few good tips Mr. H...
I have taught myself this through the years of hunting and especially the last few successful years have shown it to work.

I believe that this also goes hand-in-hand with hunting a new spot for the 1st time or two.
Basically, your not "STINKING" your area up and educating the deer.
As once you leave a spot that you've hunted, sooner or later the wind will change or the Deer will feed across your path and, BAM, they start avoiding the area / trail.
The more you hunt a spot the odds start to go in favor of the Deer.
Scent control and wind is king and picking "good / great days" can be the key!
Sooner or later I will graduate from a prince to a king, maybe in 1 month to be exact...
