Filling up your tank these days can set you back $50, $100, even $150.

That’s big money. And in many families, it means something else has got to give. It could be meals out. The summer road trip. The super-sized SUV. The suburban house.

But prices keep going up. And up.

This hour, On Point: Running on empty. How American families are dealing with high gas prices.
