Yes there was freworks, until pass midnight, grrr. I didn't knew it was so popular here. Tradition coming from Asia ? There are no fireworks connected to Halloween back East.
Hallowe'en fireworks go back as far as I can remember. We always had fireworks....even as kids, it was common to be able to go and buy them by the row. Fireworks displays were plentiful, and there was always one dad, in every neighbourhood who put on a good show and taught us how to light them. You could get them at any corner store.
It wasn't until the idiots, once again, who managed to misuse things, which in turn has lead us down the familiar path....BAN IT.
