Crackpots or clear-headed realists?

Found an old "survivalist" book from twenty-five years ago (copyright 1980), and was reading the introduction.

Got kind of a kick out of this excerpt:

"It'll be possible, perhaps, in twenty years to make some sort of judgment as to whether our preparation for survival were simply the actions of a group of crackpots or the well-planned preparations of clear-headed realists who perceived the threat in time and took effective measures to deal with it." - Checklist for Survival by Tony and Jo-Anne Lesce, p. 2.

Heh.
