This from Michael Kavallierakis:
These are photos from the Hoffman Estates box on April 22nd. I arrived shortly after the Box alarm was transmitted and was there for about 2 hours. I saw Schaumburg’s tower 51 with the new graphics and saw Inverness with their new engine and utility. Also saw the new Hoffman engines at work.
