Brad Meltzer's Decoded on History Channel

Anyone happen to catch Decoded on the History Channel (guess it was a repeat tonight)? It was on the "Georgia Guidestone's" that was supposedly built back in 1979, by a member of a Rosecrucian(sp) sect. I only caught the last part of the show and there was Meltzer debunking why the Guidestone's were built. That the stones have nothing to do with 2012, and had to do more with the fact that in 1979 both the U.S and Russia had their nukes pointed at one another. Just thought that it was interesting that this episode was dated 02/03/2011. Just in time for SHTF.

I apologize in advance if this was already talked about.
