By Ourselves, For Ourselves
AnalogKid at Random Nuclear Strikes has been doing a great series on emergency (as in SHTF) preparedness, titled 'By Ourselves, For Ourselves".
He's just released Part 7, fucusing on grouping together, also known as ‘Safety in Numbers’.
The archives for the entire series are in two sections, with part one through part five here, and part 6 and beyond here.
If you haven't been following this series you ought to get on over ther and have a read. It could save you life!
