(JACKSON, Wyo) Jackson Hole residents are suffering sticker-shock as they go to fill up their cars this week. The price of gasoline spiked by about 10¢ per gallon over the weekend. Nationally, the US Energy Information Administration says prices rose about 3.3¢ per gallon. Experts say the price will continue to rise through the spring as refineries make the change-over to the summer blend of gasoline. Currently, the average of prices surveyed by Motor Trend Magazine in Jackson Hole is $3.43 per gallon, up from $3.33 per gallon last week. The average is a penny less in Teton Valley, Idaho.
