Assuming 300,000,000 people in the U.S. and Canada, and that 5% of those

these
areas a post-Collapse population density of approximately 30 people per
square mile, or about 20 acres apiece, back-to-back.

So, you are saying that after the collapse, my neighbors biceps are
going to mutate into such freakishly large proportions that they will
be able to throw rocks 20 acres?


Can you say.....trebuchet....? That would do the job quite nicely.
Quite low tech to boot!
