This from Steve Redick; Century Lumber fire at Diversey and Clybourn, June 6, 1978 went to a 3-11:

Here’s a real blast from the past. I recorded this using a plain old cassette recorder and microphone held up to the scanner speaker while I was living at my grandparent’s house. It has held up pretty well over the years. I recognize Art Benker on the main radio at the start of the fire, and the Division Marshal was Joe Brichetto, my dad’s boss when he was in the 10th battalion. You can hear the water task force and the fireboat as well as some talk about Big John and Little John … ahhh those were the days …
