SAN ANTONIO – Drivers can kiss $2 gas goodbye this Valentine’s week as the price of unleaded continues to fall. Prices fell a nickel in the past week and 19 cents in the past month. Analysts say fears that the coronavirus will hurt China’s economy — and appetite for oil — have pushed crude prices lower. That means lower prices at the pump for folks topping off their tanks. At several gas stations on the Northeast Side of town, gas was posted at about $1.86 a gallon.
