My husband and I were sitting on the couch watching TV when I heard a loud explosion! I looked up and saw flames burst in the air with a lot of dark smoke. At first it looked like it might have been in the front yard of the house, but the flames soon engulfed the entire area. I could hear people screaming, a dog barking and I was so afraid the people and the dog were unable to get to safety. I did not call 911 because I wouldn't have been any help with the location of the incident.
