We had those in Michigan. Except some activist group said to not observe them, because when the people were taking up the slack, it gave the factories no incentive to cut down on their emissions, which were really the bulk of the problem.
Never fact-checked that.
For ozone, I don't think that's true. A huge chunk of the problem is automotive emissions; if people take public trans on those days, it does help.
My husband took public trans yesterday. He discovered that CalTrain waiting areas are not air-conditioned and arrived home as a miserable overheated lump. Today he drove.
We have color coded days around here (predating the terrorist danger color system). Code orange seems to be the equivalent of a Spare the Air day. Code red means Spare the Air and reconsider breathing it. We haven't had a code purple yet, but it's basically stay inside and pray.
I so don't get the "stay inside" thing. I'm breathing the same air as outside, neh? It isn't as if I have a whole-house filter.
Betsy, I think it's probably recommended so people stay out of the heat and/or sun.
Public transit is free during certain hours on Ozone Days in Milwaukee.
BART is free for the first five Spare The Air days here. But not Caltrain. (BART is the shiny fancy subway that serves the northerly bits of the Peninsula, the East Bay, and SF; Caltrain is the ordinary train that runs on freight-train tracks from the Peninsula to the City.)

I think the assumption around here (NC) is that folks inside will be running their AC, which often does come through a filter. And if you're staying home you're not driving hither and yon.
Re: Jonathan Strange. I'm glad a Buffista or two are planning to read it. I'll look forward to hearing about it. There's not sign of my library getting it in any time soon, but with any luck it'll show up in a month or two.
I've been on the edge of my seat about this one for at least a month. It looks like a book designed for me.
Well, that was only partly successful. I went to the Ferry Building instead, because there's a Book Passage there, but they were out. Out!
So instead I bought a very tasty quesadilla at the new gourmet Mexican place and came back to eat it at my desk while reading "Lust Over Pendle". (Which I am, btw, enjoying immensely. The narrative voice is quite enchanting.)
