Reminds me of tree trimmers. None of them know what they are doing. If you don't believe me, drive through the neighborhood (one who can afford tree cutting services), and look at the hack job they have done to all the trees. Mangled and twisted hollowed out trees where it's obvious that little thought and no foresight is the method of operation in the industry. They come in with big trucks, strong men, heavy loud equipment and a sales pitch, and that, is what gets them paid.
Funny how people want to do the same thing to weed.
