While gasoline prices remain relatively high here compared with prices seen earlier this year, surveys by AAA Auto Club show that Wyoming’s average is still the lowest west of the Missouri River. AAA’s Fuel Guage Report shows Wyoming’s current average for a gallon of unleaded regular is now $3.46 per gallon. Gasoline can actually be found slightly lower than that at some service stations in Jackson Hole where the average is now $3.49 according to Motor Trend. Across the pass in Teton Valley, Idaho, gasoline averages $3.58 per gallon of regular. Nationwide, AAA says the average is $3.38 per gallon with the lowest prices to be found in the southeastern states.
