Families WRAL spoke with say they are spending about $22 a week right now. Some are getting help paying the bill. Without that help, some say they would be out of luck.
"That's a lot of help, cause if we had to pay for it, we'd have to pay $12 a tank, and that's something don't have," said flood victim Lillie Burton.
The Department of Social Services is helping defray some of the fuel costs. Church groups are also helping.
The M&S Oil Company from Sharpsburg had been swapping out tanks three times a week before this cold spell; now, they are at the park every day.
