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.
...I am not skilled to understand, what God has willed, what God has planned, I only know at His right hand, stands One who is my Savior....
