Pennsylvania motorists won’t have to dig quite so deep into their wallets this week as they top off the tank. As reported by Triple-A, the average price for a gallon of regular fell last week in the Keystone State to three-dollars-35-cents. Here in Blair County, the going rate is three-dollars-55 cents. Meanwhile, the national average is at three-eleven a gallon. Gas prices are currently lowest in Mississippi at two-68-a-gallon. Hawaii still has the highest gas prices at four-55-a-gallon.
