I use a 3" binder w/instructions on what to do if I am home AND if I am gone (2/3rds of the year).

I consider Nuclear War Survival Skills; Chapter 4 Evacuation; to be a most important part of my book.

I am trying to find time to write the applicable parts of my Active Duty notes into a book form. That includes various radio freqs, codes, CBR info, etc.
