Listen, you cant shoot a deer if you are not in the woods. Of course hunt the wind, but show me one spot around here where the wind doesn't shift all day long. I have several stands in all areas to TRY to accomodate the wind. Half the time deer come in from a totally different direction than all the sign shows.
If you are not confident with the treestand during a particular wind, set up on the ground in the same area to deal with the wind. Its better than not going. Or sit the stand anyway. Even if deer spook,. you will learn a lot, and possibly get a shot anyway.
Also, thermals will many times carry your scent OVER the deer. I count on thermal currents ENORMOUSLY around here. I hunt tight spots, so if the thermals are lifting, I can effectively hunt a bad wind with success.
Get in there and hunt away James!!!!!
