If you want to annoy your neighbors in the morning, blast it around 6am.

There has been construction work near my house and i always work nightshifts. so i go to bed at 6> am.
Nothing is more annoying then construction workers turning up early (7:00~7:30) and start up a Loader or small/mini digger and move it to site.. .. before they are actually allowed to work (8am)..
