More specifically.. a lot of what is written in survival manuals is read in and reproduced from "FM21". <img src="/images/graemlins/grin.gif" alt="" /> I have seen the same information reprinted so many times (often even verbatum) that I lost count a long time ago. Fortunatly it is good, solid infomation so it does me no harm to read it over and over since it helps to stick it in my long term memory. <img src="/images/graemlins/cool.gif" alt="" />
