SPOKANE, Wash. (AP) - Calmer winds and cooler temperatures are helping firefighters battle wildfire that's charred hundreds of square miles in Washington state and is the largest in state history.
    
The blaze in north-central Washington has burned about 379 square miles, but one fire spokesman says "There is optimism in the air" now that conditions are improving.
    
The fire is still just two percent contained.
