Old Home Day became an annual event that both newcomers and older town residents looked forward to eagerly each year. In 1971 the Londonderry Historical Society was host to historical societies from all over the state. This year, the Historical Society will again be offering visits to the Morrison House Museum free of charge from 10 a.m. to 3 p.m. on Saturday, August 20th, for tours of the 1760 Morrison House, 1859 Parmenter Barn and c. 1840 Clark Blacksmith Shop. As they did last year, the Historical Society will again be hosting the 3rd New Hampshire Regiment on the grounds of the museum. The group will be conducting a colonial encampment which consists of pitched tents providing a cooking demonstration, military drills, cannon firings and possibly a doctor giving a demonstration all under tents. The drills and cannon firings will be happening throughout the day. The 3rd NH Regiment will also be marching in the Old Home Day parade.
