This from Eric Haak:
The Chicago Heights Fire Department had a MABAS Box on Saturday morning (2/6) for a fire in a Walmart that is under construction at 21000 S. Western Avenue. As far as I could tell, it was probably construction materials on the interior and did not involve the structure. There were two aerials up and ready but no water was used on the roof. I was not allowed to get any closer than the construction fence so the images you see here were taken from a distance. Was able to at least shoot a few rigs.
