There were no reports of any injuries or damaged structures in the fire, which was largely contained by 8 p.m. Saturday. The fire did come close to homes on Concord's far east end.
The cause of the fire was under investigation, but firefighters said it was aided by low humidity and, especially, by sustained strong winds.
