i read an article that said penned deer could smell a hot doe in the wild walking the tree line at 485yards away
i think thermals and humidity definitely play into this the more humid the better the scent lingers.thermals may blow scent up and away from the primary wind direction.one of my favorite tools in the bag is a corn starch filled wind checker ,i squeeze that all day ,you'd be amazed at what the thermals are doing as the day goes on
Now therefore take, I pray thee, thy weapons, thy quiver and thy bow, and go out to the field, and take me some venison.
Genesis 27:3 "The thinking deer hunter should mature through three phases during his hunting life. First phase, "I need to kill a deer." Second phase, I want to harvest a nice deer. And last phase, we must manage this resource so our children and their children can experience the grand tradition of good deer hunting." - Jim Slinsky
