My neighbour’s large maple tree at the front of their house was growing threateningly close to the front second story window. Pruning of the limb was in order. As this limb was quite large there was a discussion about calling in a Canadian or Chinese arborist. The Canadian arborist would come in with a large cherry-picker style truck and crew, and complete the job safely. Of course they would be much more expensive. The Chinese crew they chose came in with a ladder, rope and a small electric chainsaw. At least they had some climbing equipment and safety harness.
