Hey guys, I,m new to the forum and looking do further my tree work/care ability's. I have been operating saws for many years doing firewood and clearing property for my father and sister felling and bucking trees.I have some climbing equipment and am quite comfortable using it. I have worked dragging limbs and being a grunt for a tree service but the guys were hacks to be truthful and worked entoxicated. Not my comfort zone. Can anyone offer up some good books on climbing ,rigging,and such. I have been studying the biology of trees for a while now and thought that was an important starting point. Now I would like to learn the other science's of this industry. Aany help would be greatly appreciated
