Results of more oil being pumped overseas and less gas demand with the summer driving season near its end have enabled area drivers to fuel up their vehicles with a tad less expense.Some area travelers have noticed the slight decrease and say it's about time for gas prices to decrease. In the first part of summer, prices were $1.60 per unleaded regular gallon nationwide but they've recently slipped to $1.46 a gallon.Earlier this year, the Organization of Petroleum Exporting Countries, the group of overseas countries that produces oil, didn't produce enough oil to meet demand and prices increased by the end of April and into early May, said Michael Shanahan, American Petroleum Institute spokesman.The price decrease occurred because more oil has been produced by OPEC, mostly in Saudi Arabia, Shanahan said. Prices have declined nationwide within the last three weeks, he added.Also, there's less of a gas demand with the summer driving season
