On Tuesday night, a huge vacant warehouse on Chicago's South Side went up in flames. Fire department officials said it was the biggest blaze the department has had to battle in years and one-third of all Chicago firefighters were on the scene at one point or another trying to put out the flames. Complicating the scene was the weather -- temperatures were well below freezing and the spray from the fire hoses encased everything below in ice, including buildings, vehicles, and some firefighting gear. The warehouse was gutted, but the fire was contained. Fire crews remain on the scene as some smaller flare-ups continue to need attention.
