All I know is.....

I put out minerals last year......MINERALS.....that I can't even detect an odor......and I had 37 game cam photos the first night.

You can talk about all the scent-elimination/scent-free stuff you want.....but they need that degree of olfactory prowess to survive....and they are good at locating both what they need....and what they need to avoid.

If I hunted where there was little to no human/human-related/domesticscent present......I'm not sure I'd kill one or even SEE one.
