Gasoline prices are edging up. Prices in Oregon increased 6¢ over the last week to $2.71 a gallon. Marie Dodds with Triple-A says higher crude oil prices are driving gas prices up. Some analysts think crude will continue to rise toward $90 a barrel by the end of the year which will cause gas and diesel prices to continue to increase. The average price in Bend for a gallon of regular is $2.71.
