1. Medfield Kingsbury Grist Mill, Inaugural Party. 1 p.m. to 3 p.m. (The rain date is Sept. 29). After being gone for nearly 100 years, the water wheel was installed in May with the help of wheelwright Spencer Boyd, who constructed and installed the wheel. The public is invited to watch the wheel in motion, have a tour of the site, hear a history of Medfield mills, enjoy music from the band Route 109, and also have some light refreshments and beverages. Because parking is so limited, park at St. Edward the Confessor Catholic Church nearby, and a free mini-bus will shuttle people back and forth to the site.
