Bad news for holiday travelers. Unless we see an unexpected steep drop in crude prices, American motorists can expect to see gas prices exceeding $3 per gallon if they're not there already. As of last Friday, the national average price for a gallon of self-serve unleaded was at $2.91, an increase of around 4 cents a gallon from just two weeks ago. A resurgence in crude oil prices resulted in $8 increase per barrel. At $89 per barrel, crude is at a 25-month high. On average, gas is 28 cents a gallon more than it was this time last December. Checking around the country, Long Island, New York seems to have the highest current price at $3.21 per gallon of regular. San Francisco was just behind at $3.19. The lowest price was in Denver, Colorado, at $2.61. (CNN)
