I survived hurricane carla on the Texas coast.
My parents then moved to Alaska just in time for the Good Friday '64 earthquake. The only way off of the Kenai Penninsula was by airplane or by boat.
I was in Paris, Texas in the spring '82 tornado.
I took a direct hit to the house with an F3 in '89.
Then the fire in '90 took out three buildings and essentially everything on my property except my house.
This last tornado just missed me.
Maybe I should start buyng lotto tickets.
The fire of '90 was the worst. I lost fences, barns, equipment and just about everything else except the house and well house. Fire departments cut fences everywhere to let animals live. I had everything you can imagine rounded up in small lots on the east side of my property. Fed animals for several days. Did not know owners for all of them for over 2 weeks. Most were identified immediately and went home as soon as people could rebuild fencing.
All fencing on the north, west, and south side of my place was lost to fire. Compared to my neighborhood, I was lucky to still have left what I had left.
The "organization" I would most count on is my neighbors. They are the first to arrive and perhaps pull you out. They are there when everyone else is gone. You get a major disaster like yesterday and most "organizations" don't even know there was a house on top of that hill. Your neighbors do.
