WASHINGTON - The average price of gas across the country is $3.54 a gallon -- the lowest in three years.
AAA reports that nationally, gas prices are 18 cents less than a year ago and they've fallen 9 cents since the beginning of August.
In the D.C area, people are filling up their tanks for an average $3.56 a gallon. This time last year it was $3.72.
That could be good news for 30 million Americans expected to travel 50 miles or more from home over the upcoming Labor Day weekend.
