This from Eric Haak:

Here are a few quick images from the 2-11 at 25th and Sacramento this afternoon in Chicago (1/30). Companies made an aggressive interior attack and went defensive as I was walking up. The first image was taken only a couple minutes after the companies evacuated the building and it appeared conditions deteriorated rapidly.
