Happy Harry Truman’s birthday! Today also would have been my late wife Barbara’s 75th birthday. Our granddaughter Zoey (in the picture below) turned 12 last Monday and is now finishing 6th grade. I told Barbara I thought I would live at least to be 90. She did not make any similar promise to me.

The whole family celebrates Opening Day together at Nats Park on April 3. Because we worship at the “Church of Baseball” Opening Day is a kind of religious holiday in our household. The only time I ever missed was for my dad’s funeral and they played “Take Me Out to the Ballgame” as the recessional.
