Excerpts from the ChicagoSunTimes.com:
A tree that fell in the 3000 block of Keystone in Northbrook Sunday morning knocked out power and disrupted a gas line, creating a fire that was still burning hours after it started.
Capt. Dave Crawford of the Northbook Fire Department said crews were initially called about a downed tree, but learned upon arrival that when the tree fell it broke power lines and a gas line, causing the fire to ignite. Three hours after they arrived, the fire was still burning and the department needed to wait for Com-Ed to shut off power before they could address the gas situation and put out the fire.
