Jeff ,I find it amusing how you equate deer behavior to the laws of physics. In our world very few things are as factorial as the laws of physics.
If I say deer are brown,you will say I am wrong because once in a blue moon there is a black one even more often than black arewhite ones. I say deer have four legs , you say I'm wrong because you saw one with three legs once.
We are talking about the actions of deer that we have personally witnessed.I have not seen every deer in my woods so I guessI am wrong until I have personallyseen each and every one avoid my camera, but until then I have seen the largest of known bucks stay plenty clear of my cameras.
It is a statistical fact that by applying the actions of the majority of your targets into your hunting plan you will increase your success proportionally.
With your logic walking through the woods a takingdump is a great buck hunting plan because you saw it happen once.
