Firstly, I understand that no one was hurt!
  According toreports in The Chattanoogan , the rocket scientists blasting the hill nearby accidently blasted a "mud pocket", which blew basketball-sized rocks high and deep, hitting cars, going through the showroom roof, and hitting the Saturn dealership next door.  
Glad everybody's OK!

They are having a scratch-and-dent sale.  I'm not joking.  It was on the radio.
