McLEAN, Va. - Dogs aren't the only ones casting a longing eye at fire hydrants these days. Fire departments across the country report that thieves are twisting the brass nuts off the tops and selling them for scrap, raising concerns that the hydrants won't work when needed most.

Firefighters responding to an April house fire in Hesperia, Calif., found that the five closest hydrants were useless because thieves had taken the nuts needed to get to the water. They called in special equipment, but by the time they got the fire under control, the house was a total loss.
