10 minute average, over the entire continental United States, doesn't mean much when the air in your face is closer to an AQI of 200 than 0.

I had a neighbor once who liked to burn stuff too. First time I noticed it was when he lit off an old tarpaper shed on the corner of his property that was upwind of mine.

Years later some fireworks he'd set off caused a power outage when they shorted a transformer located at the corner of his property.

We faced off at 2:00 AM out in the street, I knew by then it was beyond time to move.
