Oh, I feel your pain…I live across the street from Admiral Safeway, and they clean their parking lot at all hours..not only a leaf blower, but a truck with brushes on it like the street cleaners.
I once had a neighbor who would actually get out of bed at night and go over and tell the manager to stop, that it had to be done before 10pm…hehehe…and they’d stop. I don’t think it ever occurs to these people that residents may be impacted by the noise.
