I read that everybody in Northern California should be prepared to evacuate. Even in the suburbs, some of my neighbors can see the flames from the SCU fire. One of these days, I would like a place in rural California where I have a chance of standing my ground. Here in the suburbs, there is no such chance, but it is easy to evacuate. I have surfed around but have found few resources on sheltering in place. I asked my friend who was a wildland firefighter if this is possible. He said, yes but he wouldn't recommend it. He survived in an emergency fire shelter when his team got overrun. I said, oh, then it can be done. He grew dark and serious and said his supervisor didn't survive. The screams still keep him awake to this day. I still think I could make something that gave you a better chance than those light flimsy fire shelters. Maybe it's a cultural issue. Australia seems to have more information on this.
