Gas Prices Down

While watching the news the other morning, I listened to them say that gas has gone done even more to less than $1.50 in some parts of the state. It has been over 3 for four years now. Then, if I heard right, they said for every penny that gas goes down, we save over a billion dollars. That sounds too astronomical to be possible. That would mean we use 100,000,000,000 gallons of gas in a day. Is that possible? With suv prices at an all time low, bet people will be out to buy.
