Fortuitous! Leitz Summicron 50mm DR

I had some time to kill this afternoon and decided to visit Harvard University's Arnold Arboretum, an old haunt from my Jamaica Plain days back in the '80s.  It has been a miserable, rainy, early spring day: some heavy showers but mostly gray and damp.  I had lined up this vista through the section where the oak trees are planted, the boughs still bare, a moody kind of image.  And then the lady with her red umbrella and boots, towing a reluctant sabachka, literally walked into my picture. A "decisive moment".  Here they are.
