Here’s a little secret about building a dry stone wall on a busy construction site: work on the holiday. I spent the Memorial Day weekend constructing a seating wall for the Hall Art Foundation in Reading, Vermont. While packs of touring motorcyclists occasionally rumbled past on Route 106, bird song was the predominant sound track. No distractions from the other contractors, who are busy there on the weekdays, meant I could concentrate on the task at hand. I built two sections of wall beside one of the galleries at Vermont’s newest art museum.
