I discovered that a person cannot get away from Cooperstown in Williamstown, and not only because Sterling Clark was brother to Stephen Clark, who founded so much in Cooperstown with their father's share of the Singer fortune. Saw a stone-and-bronze monument to Ulysses Grant (Negro Leagues star) that mentioned The Baseball Hall of Fame, and three paintings by local painter Tracy Helgeson were hanging in the front window of Greylock Gallery.
That was my third and longest visit to the Clark. If you have not been, it is well worth the trip. And there are now trails and a big reflecting pool and new galleries and study areas. I came home with books about the Clark collection, Dürer, and Owen Jones's The Grammar of Ornament.
