Cover scent works, I cut the tarcels out of my deer and use them,also save the urine, its good to use the deer urine and glands of the deer in the area you are hunting, I have had many bucks walk up on my drag, head down and following my track, I had a huge doe sneak up on me a few nights ago, walked right down my drag;) but I was so interested in the deer in the field, never heard her sneak up, she got about twenty yards then noticed me and blew, I had a bow at the time, so there was no chance for a shot, but if it was rifle season she was toast, she blew then terned broadsides to me;) I also wash in descent soap and use descent underarm deodorant, spraying down with fresh earth cover scent every couple of hours, these methods seem to work well for me, always get deer really close before they detect me, sometimes never detecting me and walk with in a ten feet of me at times, Being very still helps as well. watching your wind direction is very important due to deer tend to walk with the wind direction to there face.
