Jason10mm made a comment about fire. I will relate some of my experiences. In LA, we recently had a fire break out near the freeway at 10pm. 400 fire fighters. Helicopters. Conversely, in the last riot, I called in 3 fires in one city block and no responders would come. Our club's idyllic setting has been subject to two fires. The last one burned everything, including shipping containers, club house, benches, portable toilet within 15 minutes. The time before that, 3 fire trucks (the fire people were warned about the location) burned at the 100 yard line. 40 years ago, my mother and I drove to an area where there had been a fire and she was contemplating buying a "new lot". Every house with a shake shingle roof was reduced to about two feet of gray ash. The houses with tile roofs still stood. A couple of years ago, a fire right next to the freeway in the San Fernando Valley wiped out 150 homes. Many of the homes simply exploded long before any actual ember landed on a roof. Look at the devastation of the Civil War or any war in photos -fire. What can you do. Assuming that water pressure would be still available, I put a manual sprinkler system on the roof of the house and the garage. The weeds on the hillside are destroyed before they reach any large size. The key rooms in the house have fire extinguishers, smoke and carbon monoxide detectors. I also replaced the shake shingle roof a couple of years earlier than necessary. My preps in that area are, of course, not as sexy as buying a bugout vehicle.
