I hate those backpack blower things that the landscape maintenance guys use to push leaves / grass / dust around. HATE. They are more annoying than a piece of junk Hardly Dangerous motorcycle drive by, which is saying something. At least those things leave (eventually). The blower's constantly changing pitch and location is too loud to ignore, and too varied to numb out. It's specially designed to invade your ears. Ugh.
Planes? Fly that shit. Cars? Whatevs. Motorcycles? At least it's got two wheels. Music? Rock out. Loud 2-stroke motor blowing air? Fuck you.
