Eventually people will realize that if a deer is down wind of you, he has the capability to smell you. Now there are times that you may get lucky and they miss the scent, ignore it for some reason, or be confused by a masking scent, but the scent is still there. Just staying downwind of him is the only sure way to never be busted by smell in my experience.
Besides it might make your skin turn green and that is not my color.
