I have shot many trophy class bucks, stinking like a machine shop. If you are not in the woods you can't tag your buck. I change into cleaner cloths and play the wind. If the buck gets a wiff of you after you shower they will still get a wiff of you. Just plan your entrance, and if you plan on hunting there in the future, plan your exit. Take into consideration where the buck is bedding, where he is going, and how to aproach with the given wind.
