I'm sure someone more knowledgeable about fire fighting will be able to better address this, but I'm sure they are doing all of those things and more, Robinson. Last summer when the fires were burning in my neck of the woods, a lot of the work that the firefighters were doing involved removing brush, burning backfires and bulldozing fire breaks. Even doing all those things, they still had to put out numerous spot fires that broke out on the other side of the fire breaks. From what I heard, the fire that broke free and destroyed 200+ homes just East of Paradise occurred when several things happened at once: the wind shifted direction and intensified, the humidity plummeted into single digits all while the firefighters were working on backfires. This resulted in a canopy fire which just about tripled the overall size of the fire.
So many bugs, so little time.
