Gas prices are up -- again.
The average price of a gallon of regular in Sacramento is now $3.97, up about six cents from last week and 16 cents from this time last month.
AAA says prices could hit the four dollar mark by the end of the week and will likely level out as we head through the Summer months.
We're still well below the statewide average of $4.17. The national average currently sits at $3.63.
