One Kenny to another Kenny, I started to stalk and hunt from the ground only three years ago, although I haven't shot anything yet doesn't mean it wasn't fruitful, I have gotten to within a couple of yards from them and they didn't even know I was there, one almost trampled me. I am not a meat hunter or I would have had my first from the ground already.
Walk like a deer, sound like a deer, and make sure you have the wind and it's brezzy, go when the wind blows stop when it stops, move slow and glass a lot, you'll see them before they see you if your patient, oh, and I wear 3-d leafy mesh over my wool.
