It was eerily quiet here during the day too. I didn't hear any until around 7:40pm. After it got dark, there were a lot.

We have a new ordinance that prohibits fireworks after 10pm except on July 4 and New Year's (on those days it is allowed til 1am). But that doesn't explain why it was quieter during the daytime, and I heard very few on the prior days too - I'd expected there to be a lot over the weekend already.
