One thought on “Tornado tracks of the April 27-28, 2011 tornado outbreak”

  1. As someone who as always approached the global warming fraud from a cultural/historical perspective I can’t help thinking of The Wizard of Oz…in which Hollywood iconocized the Tornado.
    In the very early days of settlement vague accounts of super storms such as these may have been considered ‘legendary’ amongst new settlers.
    Given the Christian Fundamentalist attitudes prevalent at the time (and maybe still) these events would have been considered archetypal acts of god; mysterious, unpredictable and devastating.
    We can hardly blame those of the Green Religious Persuasion for similar linkage.
