These days, when you talk "survival," there are at least two separate arenas. One is the traditional wilderness situation, where you contend with the forces of nature and what equipment and skills you possess to live until you can return to civilization (or a reasonable facsimile) and a more normal life. The other is what is often encapsulated in the term 'survivalist', where civilization dissolves or alters substantially, resulting in SHTF (essentially unrestrained mayhem) and you need such things as lock picking skills and 45 ACP. I think this forum tends to shy away from the latter scenario, which in my opinion, is mostly fantasy.
