@wiesnerbeth ha ha! Don't be too impressed, my son was here. Didn't want to attempt it for the first time alone. Had no choice, already tried cutting through with a regular saw, but black walnut requires more power. There are at least 5 chainsaws here, I chose an electric one. So easy!
@wiesnerbeth I just realized you might think it's a whole tree, ha ha! No, just a large limb that fell in the yard. I leave tree-cutting to the experts!
