I was checking the air quality at my California abode the other day, and the first website I went to said the Air Quality Index was a lovely 40 or so. That seemed strange, given how smoky it was outside-so I tried another site: 400+. That also seemed strange, since it didn't quite look a Dune trailer outside, either.
