As a former Police Officer for Southport, I can remember one call I answered about that cannon. A man and woman that lived near the Garrison where the cannon is fired from called to complain that the cannon "upset their dog" when it was fired! They went on and on about how the dog would run and hid under the bed ETC! So, I asked them " what do you do when it thunders"??? LOL, They did not like my question and complained to the city about my question. Needless to say, it fell on death ears......pardon the pun!
