I got up early this morning to walk down to the National Mall. It’s a favorite place for me, ever since Kish and I lived in Washington, D.C. 35 years ago. It’s also a favorite spot for joggers. Why not? It’s long, and flat, with lots of interesting things to occupy your attention as you trudge along. And dawn is a good time to visit, too– especially on a day where the high temperature is forecast to hit 96 degrees.
