While driving home this morning from my masochistic cardiokickboxing class, I passed a beautiful downed tree in someone's front yard. I think it's either oak or maple. Certainly hardwood. The homeowner will let me cut it up and remove it (and the branches). Is it better to start with the top of a tree or the bottom? WIll I need a peavey or something to rotate the trunk? Not all of it is touching the ground. Thanks very much for your help.
