A gift to holiday travelers across the nation: gas prices are down.
According to the Lundberg survey, the national average is $2.60 a gallon.
That's down more than eight cents a gallon in the past six weeks.
The reason? Production at refineries is up and inventories are bulging.
There's so much gas in the U.S. that retail prices are dropping even as oil prices are up a bit.
Gas prices are still higher than they were last year, when the national average was $2.43 a gallon.
