I've read through many of the comments from previous posts. There are many pro's & con's , arguments, evidence, successes & failures. There is evidence for & against smoke, cover scents, getting s short haircut, lures, urine, chlorophyll tablets, carbon clothes, etc., etc. I've often wondered if some guys just smell different, i.e., stink, more than others. I wonder if diet & / or plain old body chemistry have more to do with it than anything else. I've never tried smoke, but it has merit. I've always tried to be clean, get a short hair cut, & "play the wind", but still get picked out when I think I've done everything right. I've got a good friend that doesn't worry too much about overdoing the scent control thing & he kills a nice buck almost every year. He wears a lot of wool, doesn't wash it much, but hangs it outside. I know of another successful hunter who has a houseful of dogs & cats, and you can tell! He kills a good deer every year as well. Go figure.
