(I hate replying to myself, but I don't see any way to add a second, unrelated reply in this new system.)

Personally, I don't care if my neighbors' use of fireworks is in violation of the law (this year, it's illegal due to "Stage 1 Fire Restrictions"). My house has windows that close and my dog, even when she's outside, isn't bothered by the noise.

About the only thing that does bother me is the use of aerial devices when we're all surrounded by ponderosa pine, it's 90°F and windy with 12% RH, and there hasn't been any significant precipitation in 2 months.
