This is too funny. We just had a friend inform us that he is recruiting is for his " apocalypse team". He wants handy people around him. So I asked, whats your skill. His reply is," finding handy people." lol This guy is serious too. He has a list of skill sets he is trying to fulfill.
On the serious note I think its very possible. I'm not worried about it thought. We have always been the be prepared type and honestly self sufficiency is not a huge stretch for us. We live pretty simple.
