I saw one of your clips from an old tv show where you talk about deer quartering into the wind. I see this more often than not sometimes, they just dont care, gene wensel said "some deer just never learn to use the wind" and I believe that to be true. Probably explains a lot of the LUCK we all saw early in our hunting career. Obviously if they were masters of the wind always, we wouldnt ever kill them but comes back to how consistent are you on mature bucks. Where I live, for every 5000 deer there might be 1-3 that are 3.5 or older but even a 3.5 here would be considered mature in my eyes.
I am not sure what I said on the TV show your reffering too. But as of now, I am convinced that most of the time outside of the rut that deer travel with little regard to the wind unless they feel they are in danger. There are some exceptions to that. But I see deer leave bedding in every direction, however, when the wind is in there favor, it seems you get a little earlier movment.
The biggest trend I see with deer moving in regards to the wind (again outside of the rut ) is when approaching a bedding spot. They seem to like to approach with wind to face. They sometimes J-hook to walk around to the downwind side then move in to the bed.
