i recently got a new farm to shoot on no one had hunted there for about three years. the bunnies had never seen or heard a gun or spotlight before. it was great for a while. my advice is if you think that you could miss leave it and move on that way they will not run away next time as soon as they see you. approach from down wind if you can. also hunting at night is good with a spotlight. a slight wind is good to cover noise you might make.
you prob knew this anyway but if not hope it helps
