You've been given a lot of great advice, though it can be hard to put it all together and make it work the field. I don't have a lot to offer but I will reiterate those points that seem important or provide a learning opportunity.
- Snort wheeze in Blacktail is almost unheard of. It seems to be a rut related vocalization, perhaps used as a challenge or as a threat. If you asked a hundred BT hunters if they've heard a buck snort wheez in the field, you might find one person who believes they have, but they are not sure. Youtube has a couple of videos of bucks snort wheezing on trail cam if you want to search them out. More than likely, what you heard that day was a deer "blowing", which is a behavior they exhibit when they've identified that you are close to them, but they don't know what you are. It is an alarm signal to other deer in the area so I wouln't try to recreate it. It sounds similar to blowing real hard into your fist, trailing off as it's breath fades. If you're busted and hear that sound, all you can do is hold motionless and hope that the animal doesn't move downwind to catch your wind. Don't move for 20 - 30 minutes before moving on.
- I agree with others, you're already doing better than many hunters. You cannot know for sure how to proceed when a new deer encounter situation arises. There are too many variables that a deer uses in deciding what it is going to do. Wind/thermals and terrain amongst them. All you can do is trust your instincts and if you fail, try to learn something from the encounter. You will mess up many times along the way.
- When you see deer or fresh sign in the woods, you should try to reason out why they are there at that location and/or what they are/were doing when they were there. Deer don't just walk around for no reason. The better you understand their daily and seasonal activities, the better you will be able to guess what they might do next.
- move less, glass/watch more. Sit silently and watch (while hidden). It is hard to fool a deer older than one or two years old. If they hear some loud or unusual noises in the woods, they are immediately focused on the source of that noise. If the noise happens repeatedly, the deer get up and move out of your way, or duck their heads in the ferns/brush so that you can't see them. Being silent and moving slug slow (thanks Jakeman) gives you a chance. You should move so slow that an observer away from your position would not notice that you were moving when they looked at you, but only that you were in a different position since they had last looked at you.
-You can't still hunt down the middle of a road. BT' bucks live in the deep and dark. You need to try to stay hidden and move (sloooowly) just inside the edges where woods/brush meet clearings. Rattling or doe bleat "can calling" occasionally as you move pre-warns any deer in the area that you are there, and helps them believe that you are a deer making the noise, not a person. Small noises made as you move will not cause huge concern to unseen animals close by.
Enjoy the fall weather. Have fun. Good luck!
