Had a guy walk into the firehouse and tell us " I think y'all got a fire or soemthin'". Walked outside to a column.Just so happened to be a first due house fire. Pulled up in the wagon with fire showing. We made an aggressive push into the house and found fire extending into the living room from the back bedroom, dining room and enclosed porch in the rear. Quick work was made of the fire which appeared to start on the back porch near a heater. Second in companies didn't get a chance to see much.
