I have thought of a decoy and they seam to be curious to the Mackenzie in my back yard.It would be a little hard to carry out though.I remembered that there is a 6 foot dead tree in some tall grass about 25 to 30 yards from where they are crossing. I am going to try sitting there next timeand see what happens. Here is the pic I took about 3 months ago in my back yard,if you didn't see it in my other post.
