I was in the woods the other day and only had on my desert camo from when I was in Iraq. No scent killer, no cover scent, just me, my bow and my camo. I had a 8 point white tail stop at 20 yards and look around and then he started coming right for me, he passed me at 3 feet and never knew I was there. I was on the ground and not a tree stand that the wind was still. I am now sceptical of spending money on scent killer, any thoughts?
