Everywhere I am there is a guy running a leaf blower. At my house, leaf blowers everywhere all day long. At work, of course, leaf blowers blowing dirt and allergens into the air. It’s such a special noise, it goes through walls and headphones so effectively. They are the most pervasive, annoying things on the planet. I hate them more than mosquitoes.
Just get a pulse jet and fire it up when they start running the leaf blower. You won’t be able to hear the leaf blower anymore.
