    In a recent press release, AAA said, “Gas prices are creeping back up just in time for the busy summer driving season. The national average for a gallon of regular is up 4 cents from last week, as the price of crude oil rises and demand goes up. Typically, the seasonal increase in gas prices starts earlier in the spring, but lower crude oil prices so far this year have kept that from happening.”
