Xenia is a suburb of Dayton, OH. The tornado was in 1973 or 1974. We lived in nearby Englewood till late summer of 1973. Shortly after our move I opened either Life or Look Magazine and seeing pictures of the devastation. That had to have been a tough one to live through!
In those days we used to railfan B&O and Penn-Central and another line, could have been DT&I, but I'm not sure.
