Changing Thermal Winds

I hung a deer stand well before season so the deer would get used to it being there. This stand always had the wind blowing from left to right when I sat in it before season. This would have kept my scent blowing back in the direction from where I came and toward a house. I was looking forward to hunting from this stand, for every year I have found some great sign around this area. As winter and hunting season came I prepared to hunt from this stand. The first time I hunted from this stand, I noticed that the winds had changed. I didn't think this was a problem because the wind blew into my face, until I got busted by deer coming from behind me. This happened every time I tried to hunt from this stand if it was cold. If it was warm it went back to the way it was from left to right. I decided that as the temperature dropped the thermal winds changed. As you hang your stands watch out for these changing thermal winds they may cost you some good hunts. As for me I learn from my mistakes, I will be able to hunt this area by moving the stand about 50 yards where the wind funnels down between 2 small hills. The wind stays the same between these hills warm or cold. Also moving gave me another view of a logging road where I have found rubs and scrapes. But moving also keeps me from seeing a pond on the property also surrounded by rubs and scrapes. I guess you just can't have everything.
