RICHMOND, Va. (AP) _ AAA Mid-Atlantic says Virginia motorists will pay the lowest Thanksgiving week gasoline prices since 2008. The auto club says the average cost of a gallon of regular unleaded gas in Virginia on Sunday was $1.92. That’s down seven cents from last week and significantly below the $2.66 that state drivers were paying a year ago. The Richmond and Norfolk areas are tied for the lowest average price at $1.88, while the Charlottesville area is the highest at $1.95. The national average is $2.08, down from $2.83 a year ago and nine cents lower than last week. AAA predicts prices will continue to fall and could drop below $2 per gallon nationally by Christmas for the first time since 2009.
