Scent and the deer senses

I can't tell you how many times I've been busted by a deer smelling me. I showered with scent free soap and shampoo,spray myself down with scent remover head to toe,and still those darn deer still sense my presence.I tell myself the wind must of shifted or I moved to much. You could soak your self in scent remover while wearing a pair of scent lok hunting clothing,and the deer will still smell you.I use to drive my girlfriend crazy with trying to be as scent free as possible.For me it became an obsession for me.But does work as good as it is to be believed. Well I can tell you this I never shot a deer until I started working on reducing my scent I'm not talking about just playing the wind,but going out of my Way to be as scent free as possible. Some of my friends can't believe how much scent prevention is always on my mind.Some think its a waste of time,but I know it helps and to me anything that helps me get a little edge on a whitetails nose is better than nothing.I may spend 200 dollars on scent elimination spray this hunting season.But I know I'll harvest a deer or two. maybe not a buck,but certainly a doe. So are you a scent remover believer or just playing the wind?
