An old buddy of mine owns a tree service business and the things I've seen him do are amazing. I once watched him in a over two hundred year old church yard take a giant oak limb, as big as any tree by itself, and rig it so that when cut it swung around the tree, missing the church it was hanging over, in between the cemetery gates, and bang into the truck, taking only two small tiles off the gate. They can do some stuff.
