Ridgefield Library is hosting the second of two gatherings about efforts to preserve the evolving Battle of Ridgefield history and the evidence and artifacts that represent it. The Ridgefield Historical Society will share what researchers have found, and hear feedback. The charrette is Sunday from 2pm to 3 at Ridgefield Library. Registration is required. Ridgefield last month commemorated the 245th Anniversary of the 1777 Battle of Ridgefield.
