Those $4 a gallon gas prices we experienced from 2007 through 2009 may be a thing of the past...at least for this summer. Economists predict that the national average price for a gallon of gas will fall about 32 percent from a year ago. Between now and September, when we do most of our driving, it should cost you much less to fill up at the pump.

According to the Associated Press and Yahoo News:

The lower prices are a result of world oil supplies growing faster than demand because of higher production in North America and elsewhere.

U.S. drivers are expected to consume slightly more gasoline, a 1.6 percent increase, during the summer. But gasoline expenditures by household are expected to be the lowest since 2004, according to the EIA, with people spending about $700 less on gasoline in 2015.

So now with the warmer months ahead and continued lower gas prices, go ahead America, go on that trip, spend a little more, and enjoy the bonus while it lasts.
