To respond to this post by Penny, I just want to say this is psychologically frightening in the sense that in all my years I've lived in CA I've gone through dozens of swarms of 3s and 4s and wondered if something bigger was on the way. Well nothing ever happened. And now we see this after this swarm. GEEEEEEEEEEEEZ. Now next time LA gets a swarm of 3s or 4s I'll be thinking we are DOOMED.
