Mature bucks only travel with their nose into the wind
100% agree.
The only time I find the statement partially true is from forced movement. Locally, if deer are used to drives on a particular property you cannot move them with the wind at their backs if your life depended on it...but that is not bowhunting, generally.
I would add...the idea that there is a clear 'upwind' and 'downwind' in every senario. I hunt broken ground and the wind swirls like you wouldn't believe. If a deer goes 'downwind' and doesnt smell you...it probably wasnt 'downwind'
That is, if you are not wearing scentblocker underpants.
