Walter and friends have done us all a great service by doing their research and making all of their interviews available for a wide audience at no cost. Thanks ! We need it ! Always stimulating, sometimes controversial, these conversations have opened my eyes to some new subjects, points of view, and more sources of information about ancient thought and technology. It's obvious.... there were a LOT of very smart people long ago, and they tried to tell us something important with their structures, stories, and symbols. If we're smart, we'll pay attention.
