I think the facts are skewed due to not all the info not being there.
Although that blind were there "for years", I HIGHLY suspect the reason the deer were keen on that position was because of the smell of human scent from other hunters in that 2 years. The reason could be because they were high strung around that blind was because it was connnected to humans... as so far as what the deer thought or smelled.
What do you think? I mean, I don't think in that two years the blind sat without any hunters in it.
