At 4:44 AM on July 17th 2011, this alarm came in reporting a residential fire.  First arriving units found a large mental machine type shed with flames through the roof but no home involved.  The initial attack provided a quick knock down to the fire, however crews had to bring in heavy construction machinery to pull the metals walls out of the way to extniguish the fire. Crews were hampered by the July heat and high humidity.   The cause is under investigation.
