This is a day in history when tornadoes ripped through Ohio, Pennylvania, New York and Ontario in 1985. I lived in Harmonsburg, Pennyslvania at the time and remember these tornados quite well.  To me the scene looked like what you would expect from a nuclear war.  There was nothing left in many places.  Seventy-six people were killed after 41 tornadoes touched down in this outbreak.
