This from Steve Redick:

Took this in around 2230 Tuesday night at 2258 S. Blue Island Avenue. It sounded promising. A metal clad warehouse butted up against another building. Interesting that the size-up was no exposure problem yet it seemed obvious that there was a high potential, in fact they reported  some fire in the adjoining building on fireground. TL 5 with the new rig as well as 28 with a new pumper and I guess what must be a spare command van.
