House fire in Chilliwack

It looks like no one was hurt in a big house fire in Chilliwack last night.  It happened on Griffin Drive behind Sardis Park….apparently neighbors said they could see the smoke, then there was a loud explosion and the house went up in flames.Four people were home at the time, but all of them managed to get out safely.  The fire department says the cause of the fire is accidental and may have been started by a cigarette.
