People planning to be on the road for Thanksgiving will find themselves giving thanks for slightly cheaper gasoline prices, even though the prices are still higher than they were at this time last year.

Triple-A’s Gas Watch shows the average statewide price of unleaded gasoline is $3.17 per gallon, down from $3.22 last week.  In Houston, the average price is $3.15 per gallon, down from $3.19 last week.

Corpus Christi still has the cheapest gas in the state at $3.10, and Texarkana has the most expensive at $3.22.  Nationally, prices are down to $3.35.

Triple-A fuel specialist Bob van der Valk says prices are down because refineries are running at full capacity. Van der Valk says prices could fall even more to three dollars per gallon or even  less between Thanksgiving and Christmas.

If you like these prices, here’s something to think about.  As low as they are nationally, they’re still the highest they’ve ever been on Thanksgiving.  The previous Thanksgiving high was $3.08 in 2007.
