I use zero "scent" attractants. IMO, it's a waste of money. You can fool a buck or two here and there, but it is by-no means "magic pixy dust" that brings them to you.

Consider a whitetail can distinguish scent down to the single parts per million. Do you really think that they can't tell the difference between fresh and bottle urine? I think it's one of the biggest wastes of money in the hunting industry!
