As someone who lived in the suburbs for most of his adult life (Delta, specifically) and who has since moved away, and as someone who lived near a field where people were popping off fireworks on Halloween, I'm definitely glad I don't have to deal with it anymore in terms of trying to get sleep on Halloween night, and subsequent nights with kids trying to burn off their supply.
Nonetheless, I don't have too much of an opinion on it now that I'm removed from it, and it is weird telling people around where I am now that this was indeed a 'tradition' in Vancouver, and seemingly confined to only the GVRD.
