RE: Scent Lock B. S.
The way I look at it, every little thing we can do to minimize the scent we take into the woods with us helps.
If that means spending the $250 on a full set of scent concealing camoflauge, do it. If it makes you that much more confident then you're going to enjoy yourself that much more.
I haven't yet purchased any scent concealing clothing, but I plan to in the future.
