Because I move around all the time... I see many types of pressure.
I hunt some public land where I'll pass 3 hunters on my way in (on a 200 acre piece)... and I have hunted some private where the deer don't yet seem to really know what a human even is.
But for the most part.. I hunt moderate to heavily pressured deer.
From the 1st day though... no I think not... but by day 7 or 8 they know things are up. The trick is not to let them know.
