MOVEMENT! Camo helps, but it won't make you invisible!
There is a big reason, deer don't like to move (in most places) during windy conditions! When "everything" is moving, they can't pick up movement easy!
Whether its camo, or scent blockers, if thats what you are leaning on, its going to fail you sooner or later!
That said, I like the original Realtree and Mossy Oak camo's the best!
I have been literally eye-ball to eye-ball with deer several times, without getting busted wearing the original Realtree!
