There may be no way to get an accurate answer, but here goes:

If you're hunting a very remote piece of woods where all the deer have never seen/smelled a human, what would the
reaction by when they got a wiff of human scent?

Curosity? Alarm? A different smell that signals an alert or maybe no alert?

I would think that since it is not a natural scent in the woods the deer have always lived, they would react the same way deer elsewhere do when
they pick up the scent of man.

Just my .02...
