For those of you who aren't you are missing out on one of the joys of deer hunting. You wouldn't believe how hard it is to pick out a deer in the woods if it ain't moving. Ive had em at 20 yards and couldn't see em, my dad thought I was crazy until we found out. Blood trailing is even worse, I've watched deer fall and couldn't follow the blood trail. At least I still got my ears, may not be able to see em but at least I can listen to them walk by.
