I had something interesting happen on the way home. I was behind a truck with one of thoes "in memory of" decals on the back window. (Do they do that anywhere but the South?)
It said "In memory of my sister Georgine Corrigan who was on Flight 93. September 11, 2001"
I've never seen one of those.
Lots to think about.
