re: So, the only recorded F6 tornado hit Louisiana and Mississippi in 1840?

Highly doubt the winds were anywhere NEAR the claims. They no way to really know. So this is a classic case of cousin tommy live through that last Nader and it was well over 150 mph. And he told me this one was TWICE as strong as that one. Tommy ( by now a town celeb) is declared the judge of all things winds with his miraculous good eye.
