EIA: “Memorial Day weekend is the traditional start of the summer driving season. Leading up to this year’s holiday, the national average retail price for regular gasoline is $3.67 per gallon (gal), as it was this time last year. After increasing 42 cents/gal from early February to $3.71/gal in late April, gasoline prices have fallen modestly in recent weeks as increasing refinery crude oil throughput and higher imports have added supplies to the market.”
