What a difference 6 months makes

This recent picture is a sign that is outside a gas station that closed about 2 or 3 years ago near my house. About 6 months ago, when gas prices were $4.30, we would drive by this station and think about how nice it would be to pull in and fill up for the price on the sign. Now 6 months later, no one would even go to this station because those prices are too high. I don't think anyone could have predicted prices coming down this low, but it would be nice to see it get below a $1.00 a gallon.
