This from Larry Shapiro:
I was in the neighborhood when the 7th Battalion pulled up on a working fire in a three-story, brick apartment building at 3111 W. Diversey. They had rear porches going with extension to a two-story house behind the building on Troy. He asked for a Box Alarm and companies made quick work of knocking down the fire.
I arrived before the Box Alarm companies to find crews washing down hotspots.
