They have hell with fires out there.
Yes indeed. Here is a report about So. Cal Edison Co. stating they have had "circuit activity" near the fire's origin. I'm not sure what they mean by "circuit activity," but I do know that electrical sparks in super dry areas, brush, Manzanita, scrub oak, etc., can result in huge fires.
