If you're headed to the gas station take some extra money. Prices have taken a dramatic hike since the weekend. Even as we drove around Washington Monday, gas prices were increasing faster than people could fill up, going from about $2.48 a gallon to around $2.57 a gallon, for regular. Just a year ago at this time it was $1.85 a gallon. As of right now the average price of regular gasoline nationwide is $2.61 per gallon.
