The wind is the most critical issue for big buck hunters but it all depends on what kind of hunting you do. Looks like gunplummer is from PA and they do a lot of stalk hunting in those big timber areas. If you walk around in big woods then all you need to worry about is the wind directly where you are at that moment. I would say most around the country are confined to smaller parcels of land and many hunt from stands. If you hunt from a stand you need to have the wind favorable or you won't consistently kill good bucks. I have lots of friends that give the "uncle smokes and killed big buck on stand B.s.". You can't do that consistenly. Sure you can kill 2yr old bucks that way. But you will rarely shoot mature bucks that way from a stand. Most fully mature bucks try to get the wind in their favor but they can't always do it and thus you need to try to hunt the areas that they can't have he advantage. Maybe a deep creek to your downwind side or a roadway or something. Try to get the wind favorable for the deer but more favorable for you and you will be successful.
