I get far fewer days deer hunting than I would like, and it takes me over 1.5 hours to get from my front door to my closest tree stand. So if I am improving my odds by only 5%, it is still worth it to me.

Its like the saying "I'd rather have it and not need it than need it and not have it." I'd rather take the precautions knowing it might be pointless than not do so and risk getting busted by the biggest deer I see all season. At least when I get winded I know there is nothing else I could have done.
