Gas prices drop in Houston

Gas prices started to slide Saturday. This week, oil prices plunged by almost $17 a barrel, and that means lower prices have already started to show up at the pump.

In Houston, the average price for a gallon of regular unleaded fuel was $3.87 Saturday morning.

That's a penny less than what it cost to fill up Friday.
