You'll pay more for gas than you did last year for this year's Christmas road trip. Last year, the average price on Christmas weekend was $2.09 per gallon. Today, the average is $2.37 a gallon. If you're in the high country, the prices are higher. Aspen stations are selling mid-grade unleaded for $3.34 and $3.79 per gallon. Patrick DeHaan with Gasbuddy.com says gas prices are up from a year ago because of production cuts made by OPEC.
