the thing that gets me about ALL of these doomsday people......they almost ALL think they're gonna bug out. some have what appear to be really well laid out plans to do this. what not a single one of them take into account though, is that if they feel the need to bug out, so will the other half a million people around them. accordingly, IF anything happened that caused them to feel the need to bug......so would everyone else. they'd be leaving the relative safety and defendability of their home to sit in a traffic jam in a relatively unsecure, undefendable vehicle.
this of course if presuming that anything that bad did ever happen though.....i feel that to be highly doubtful though
