I wanted to relay an experience I had about 4-5 years ago...I was hunting in eastern NC, over a large soybean field, I was about 20 feet up in a tree, thinking the wind was perfect, southeast coming from my back, which is where the woods was situated, blowing my scent into the field....Deer in this stand usually come out into the field from another woods line to the east, about 100 yards from my stand and feed toward me...

I had been in the stand about 15-20 minutes, when about 350-400 yards out in the field I noticed 5 white triangles out in the beans....I picked up my binoculars and there were 5 does with their noses straight up in the air....After a few minutes of getting a good wiff of me, they ran into the woods...

Yep, our scent is heated and it does go up, for awhile, but it eventually cools and comes back to the ground...
Any of you guys grow up in the country and see what happens to smoke from a chimney??? Days with a high barameter, it goes up, days with a falling barameter, it comes out of the chimney, then slides down to the ground, same as when its raining...

We can't "beat" a deer's nose...Think about it, they can walk through the woods and with their nose they know that some local dog passed by 7-8 hours ago, they don't need to see it, they know it....The best we can do is to eliminate odors that we emit as well as we can and set up so the wind isn't blowing from where you "think" the deer will come from, this is learned from experience, but you will never be right 100% of the time...

I have often said this..."A deer can see you, and not know what you are....A deer can hear you and not know what you are....A deer can smell you and know where you are, how far away, what you had for breakfast and what color underware you have on"...
