"The age of the volunteers is increasing dramatically," said McKenna. "The average age of a volunteer in the United States now is over 50. That's scary, because we don't have our younger folks coming into the service like we used to," he said.
Meanwhile, McKenna is continuing to urge residents not to burn anything outdoors until the area receives a significant amount of rain.
He said so far this week, two structures have already been lost to brush fires. One of the homes was abandoned, but the other was occupied. No one was injured.
