All the gardeners use them, kick up a sand storm of dust that they blow from one house to another, until the latter's gardener shows up with his battalion of leaf blowers to blow the dust back again.
Then there's the noise. Thursdays in particular, at least a half dozen different gardeners on the block at different times. It sounds like the deck of a WWII aircraft carrier. The noise is six days a week.
I have a black car and cannot keep it clean, thanks to the gardeners and their danged leaf blowers.
