The 9 o'clock cannon in Stanely Park. Originally installed to defend Canada from any attempts by the United States to invade, it now serves as a very loud kookoo clock. Stupid me forgot to turn on the audio recorder so no audio on this... Though who knows, perhaps all that would of registered is static. Even with ears plugged I was close enough to have my ears ringing. Neatest part afterwards was how the echos of the blast kept returning for about 10 seconds.

I'll have to go back sometime to get that audio.
