I have a pulley system out in one of my trees in the back yard that I created. Go to a hardware store and buy some of that metal cable that is Rubberized on the outside and buy a good solid pulley. The rest is pretty self explanitory. Hang that from your ceiling. I use an old closet pole about 4 feet long and I cut a hole in each of the deer's hocks and slide the pole through.
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
