We were setting off fireworks in the street in the middle of the afternoon (cause you'd buy a bunch and gradually deploy in the days leading up to the event). We shot off a rocket, which was one of mine. There were fire trucks shortly after putting out a blaze in an open lot. 1980s, I was <10 years, my older brother and his friend were pretty sure we caused it.

I have no way to know if we started that fire, but regulations exist for a reason and people who live in at-risk areas understand that they could lose their homes.
