>>And we already have more than enough leaf-blower operators for years to come.<<
I have issued “shoot on sound” orders to select operatives for leaf-blowers who run before noon.
(fact: in most California municipalities Leaf Blowers are illegal. But you can ask the leaf blower if it is illegal, not so the wielder).
The (legal) Mexican guy who mows my lawn hasn't heared of that...I can always tell he's here by the loud whine of his blower....
