Tourism this weekend could see more travelers this year than last. According to AAA Auto Club, 1.6% more residents here in the mountain states plan to take trips over Memorial Day Weekend than compared with last year. That amounts to about 2.5 million residents of Arizona, Colorado, Idaho, Montana, New Mexico, Nevada, Utah and Wyoming. Meanwhile, gasoline prices, which shot up about 15 cents in Jackson over a week ago, have not made a significant move downward again despite declines elsewhere in the US. The average price for a gallon of unleaded regular nationwide is now $3.68 per gallon according to AAA Auto Club’s Fuel Gauge Report. Meanwhile, the report places Wyoming’s average price at $3.63 per gallon. The lowest prices can be found in South Carolina where unleaded regular was selling for an average of $3.35 per gallon. AAA says oil analysts are blaming a refinery slowdown due to maintenance and other problems in the western states for the rise in prices here as compared with the southeastern states. In Jackson Hole, prices currently average $3.71 while the average in Teton Valley is now $3.86 per gallon of unleaded regular.
