This from Steve Redick:
Evanston Box Alarm at 635 Sherman Avenue. Three-story, multi-family apartment building. Looks like whatever rig has spare Engine 25 dropped a big supply line down the alley and gave it a good whack with the deck gun. Fire was blowing out the 2nd floor rear and got the porches going and communicated to an exposure building from what I could see from the remnants. I also notice a big solar panel array on the roof that must have made venting very difficult. The positioning of the aerial through the trees was well done. This was also my first view of the new Skokie tower. All the images and a brief video can be seen here
