You can tell the neighborhoods with the most fireworks (legal or illegal) by the PurpleAir air quality map... #LosAngeles #July4th

@ai6yr JFC. The one nearest me must be located weirdly because it says 47. The next closest are 157 and 189. There is a spot in my town at 220!

ETA: There is a spot in Santa Ana that is approaching 500. Yikes!

@SRLevine Undoubtedly it's inside and not outside, even though it's marked outside.
