I wish I had a picture. When I was still in my teens, living at Mom and Dads house, There was a nice Oak Tree in back of the house. Had a very nice large limb, protruding at 90 deg, about 8 feet from the ground. I had a chain and a come-along hanging on that limb, bout 6 feet out from the trunk. Pulled and installed untold engines from that tree, even pulled inboard engines from boats I owned. I had never heard the term " Shade Tree Mechanic " until my Dad started calling me that.....True Story... R.I.P. Dad....
