That was going to be my next question, but then I remembered that unless it is a beach community, fireworks laws are usually statewide.

That's right, they're statewide.

There is a cop and a police chief who both live fairly close to my in-laws house, where I do it every year. They're aware of what I do and have never said a word.

My undertanding is that the police don't go looking for violations, but they will respond to complaints.
