On December 6 1917 Halifax Nova Scotia was devastated by the largest man made explosion to that date. Boston immediately sent medical aid and building supplies in response. To this day we send a Christmas tree in thanks for what the city did. Very few families were unaffected and a hearty thank you for what your great city did
