I NEVER had to deal with fireworks when I lived on the East Coast. I now live just outside Seattle and there were giant explosions on my street from 4 PM until 2 AM. And they're banned but no one cares and it's not enforced.
I have lived in the Seattle area for more than 35 years, and it's gotten worse and worse as time has advanced.
Bans do nothing if the PD won't enforce them. And very few local PDs even make a token effort.
