RE: Barometric pressure and deer?
Speaking strictly from my experience regarding only the activity of non-pressured deer in the High peaks region of the Adirondacks, 30 days or more after the fall solstice, the advent of low pressure sends then seeking cover. Particularly when following several hours or more of tight isobars, which tends to signal the poop getting ready to hit the fan. This is when I like to take a stand in an area I have selected for just these conditions, hopefully intercepting them on the way.
