There are two shows that I have been enjoying over the last year... Jericho - the story of our country that has collapsed because of power hungry political bastards utilizing a Black Water mercenary group to cause the conditions which would allow them to take over. (A scenario that I have no problem envisioning.) And Jeremiah - the story of our country that has collapsed because of an engineered biological experiment gone bad and killed off everyone who had reached puberty. (A scenario that I have a little more of a problem envisioning.) In both shows it is interesting seeing how the various elements of our society react to the ensuing conditions. But an interesting idea was brought up in Jeremiah. In one episode there was a bar/pool room where the owner kept track of people. When someone came through and had stories about where they had been - where they were going - who they had seen where - who they were looking for - etc, the 3x5 file cards and push pins in a map kept track. After our upcoming catastrophe, whatever the form it takes, how will we communicate and locate others? Assuming there are no computers, phones, cells, mail service, etc? ... CB radios, Ham radios, word of mouth, ??. Has anyone given thought to this? Any suggestions - or have heard of any kind of "bulletin board" for what might work? Or would it all be a bad idea?
