Nope and do not care to. If they did work they would take some if not all of the "hunt" away for me. One good use they have is if you are paying to hunt (leasing, guided, outfitter, etc.) then they can give you a feeling that what you are wanting to kill is there. I would not want to know the location the picture was taken in though, I would just want to hunt. One thing I enjoy about hunting, is, well hunting and to me using cameras takes away from "hunting". I know there are good deer that use most places I hunt, I don't need a trail camera to get me to hunt, I love to hunt. I still say from the hundreds of pictures of bucks I have ever seen, I personally know of none that were killed using the "pictures" and that is all I need to know. I have nothing against them being used, but I don't and probably never will.
