My guess is that these incidents are the result of an experiment in atmospheric depredation. I remember when the bird deaths in Austin, Texas were in the news a while back - Alex Jones lives there and I remember watching him on his public access TV show explaining that almost everyone he knows in Austin was ill to some degree or another. I live in Dallas, Texas and last Saturday, for about an hour or so, there was this eerie dense dust cloud that filled the air. My gut feeling is telling me that we're going to see a lot more weather anomalies this year.
