MODESTO -- Gas prices continue to edge down in the Northern San Joaquin Valley.
After spiking more than 50 cents a couple of weeks ago, gasoline prices have shown a steady drop since Gov. Brown ordered regulators to allow the sale of winter-blend fuel earlier than usual this year.
The national per-gallon price for regular unleaded, according to AAA, is $3.78 today, down a penny from Sunday. California continues to lead the nation, with an average price of $4.60.
