Ohio’s gas prices are up for a second straight week. The state average is $3.36 for a gallon of regular gas in Monday’s survey from Auto Club AAA. That’s up 5 cents from last week but still a dime below the cost of a year ago when the average was $3.40. The National Average is about $3.34 Monday. That’s up a penny a week ago, but still well below the $3.68 average at this time last year. The lowest average in Ohio Monday is $3.24 in the Canton-Massillon area. The highest was $3.41 in the Cincinnati area.
