Three new tree fences will be dedicated in memory of Elisabeth Lay on Wednesday, September 20 at 4:30 pm in front of her home at 239 Marlborough Street in Boston. The fences were given by her fellow members in the Back Bay Book Club, with additional support from individual members of The Garden Club of the Back Bay and The Neighborhood Association of the Back Bay. Rain or shine. Tree fences are a fitting tribute to neighborhood activists, and anyone interested in learning more about the tree fencing project may contact Anne Swanson
