I' m thinking an earth scent where there is snowfall may not represent the surroundings too well. I have used the Fox urine stuff of different brand names a few times. I have seen more deer with that than most other camo scents. One time a fox came running at me at about a hundred miles an hour! I think those were the plastic wafers. I have rubbed horse crap on my clothes, while hunting near a horse pasture, (make sure it' s not too fresh)! It seems like smoking seems to mask human scent. A few people in my party smoke cigarettes in their stand. They don' t seem to have a problem taking deer. They think since it is farm country, where people burn wood, it kind of fits. Who am I to say? I can' t say I get deer every year.
