Not much change in gas prices over the last week. Marie Dodds, with the Triple-A, says prices are about 40¢ higher than a year ago. “Gas is going to cost you a lot more this holiday season than a year ago, when our national average was at $2.59 and in Oregon we were at $2.71.” Diesel in Oregon is running about 3-37 a gallon. This is normally the low point in prices, so if the economy continue to improve. It's possible that average prices could move about $4.00 a gallon next year.
