All I have to go on is the research. Maybe their right, maybe their wrong. It gets deep and hard to imagine the levels they are talking. Then there is the 2nd sense of smell if you will in the Jacobson's gland. Both dogs and deer have it but is it really fully understood? I just believe if a deer (or dog) gets down wind and is paying attention, it doesn't matter what you showered in, clothes you're wearing, or spray you used, it will smell you.
