If I were to bug out, I would bring my US Army Ranger's Handbook and "The Book of Bo-Vol I".

I'm sure most people here are familiar with the Ranger's Handbook.

Nobody here is aware of "The Book of Bo-Vol I" because there is only 1 copy in existence at this time and for the foreseeable future. It contains astronomical data, SS HF radio frequencies, and many other items that are applicable to bugging out via land and more that is applicable to bugging out by water. Basically, it has 22 years, 5 months experience of USCG service in it.
