SPOKANE, Wash. -

Good news and bad news for eastern Washington drivers this holiday weekend. The good news? Spokane has the cheapest gas in the state. The bad news? Washington has the fourth most expensive gas in the nation.

AAA says Spokane drivers are paying an average of $3.80 right now. It's just a nickel more than last 4th of July. But, if you're heading west, be prepared to pay up. Gas in Seattle is about $4.06/gallon of unleaded. And, only Alaska, California and Hawaii are paying more for gas than Washington.

Heading east will save you money. Idaho gas prices are lower than last year at this time. Filling up in Coeur d'Alene will set you back $3.60 a gallon.

While prices tend to dip slightly before this holiday weekend, the unrest in Iraq has driven prices up. In fact, they've gone up every day for more than two weeks. But, GasBuddy.com says, barring a nasty hurricane season or other unexpected event, we could be paying seven to 10 cents less by Labor Day.

Consumer Reports says there's one simple thing you can do right now to improve your gas mileage: slow down. Going from 75 mph to 65 mph can save you five to seven miles per gallon. Though, we can't be responsible for the honks and tailgating from other drivers.
