Things that interrupt my sleep.

So this morning at around 5:30am, I was awoken by an enormous boom.  At first, I thought it might have been thunder, but it sounded too metallic.  Then it happened again.  And once more.  So I dragged myself out of bed to look out the window and what do I see?  A dumpster delivery truck dropping off a dumpster across the street- at 5:30 in the morning.  If it was thunder, I wouldn't have really been able to complain, but aren't there laws against loud construction and deliveries before 7 am?  I know in Santa Barbara there are.
