This from Eric Haak:
On Saturday, November 19th, the Chicago Fire Department responded to the report of a house fire shortly after sunrise. The Englewood Fire Alarm Office had received two different locations and the first engine arrived at the first address with nothing showing. The alarm office advised they were also getting calls for 74th Street and Engine 54 landed with a fire a few seconds later. The residence was occupied but no one was at home at the time. The last photo shows a little modification made to a spare rig.
