We try not to spend too much time eyeballing the price of gas, but occasionally the wild variations in price hit a point where it warrants an update. Today, the national average price for a gallon of gasoline hit $2.50, 12 cents higher than last week. That significant spike is just a prelude to higher prices for the spring and summer travel seasons. There’s also the switch to a different type of gasoline for warmer months, which adds to the price of gas. Believe it or not, some analysts say a weaker stock market and economic uncertainty could bring gas prices down. That’s one of the oddest silver linings we’ve ever come across.
