Gas prices are down ahead of Labor Day travel

If you're driving to your destination on Labor Day, gas prices are 90 cents cheaper than this time last year. The price of a gallon of gas in Arizona is $3.45 a gallon. It's a penny more in Maricopa County. GasBuddy on Thursday morning revealed at least one station, an ARCO in west Phoenix, where gas was below $3. If you're heading north to escape the heat, gas prices in Flagstaff are $3.57 a gallon. Experts say lower demand and a quiet hurricane season are keeping oil prices down.
