Ummm shouldnt that be the case anyway.
Make your own plan, and prepare accordingly.
Two great ideas or suggestions for when a huge disaster hits, mad-made or natural. Not having anyone other than myself to look out for I could be one trying to help others but honestly depending on how large or potentially severe and long-lasting such a thing might be I might be better advised sticking closer to my own home.? I kinda doubt things have changed much since 1972. Maybe worse today?
