Early on, I was interested in "survivalism" as part of a life-extension effort but as my piano-career developed, I lost contat with that idea. Now, however, it seems that with the Covid-War, the idea is back. Dave Pizer's VENTUREVILLE just north of my position in Pheonix collapsed several years ago-- but would have been ideal for the coming economy collapse. As it is I'm stuck in Phoenix. Here's a newsletter recommended by Mike Adams... to start my thinking off in the "survivalism" direction again.
