Would these fires really not have started without PG&E as the most proximate source? The Mendocino Fire Complex, the largest in CA history, was sparked by lightning. Another fire was started by someone sparking it by hitting a metal spike trying to seal a wasp nest. If it wasn't PG&E, it surely would have been something else. The forest was/is a tinder keg waiting for a spark of any sort.
