It wouldn't be the asphalt scouring, the EF3 in Americus, GA on March 1st, 2007 scoured the pavement. I remember seeing something in the survey for the Philadelphia tornado that said that a mobile home was thrown 300+ yards without any sign of a ground impact in between, after which it was obliterated, with the fatalities occurring here as well.
I've gone through this thread multiple times since I joined the site and it is always a worthwhile read.
