another thing I read about that time, QA, was I guess in major cities they tried varying shifts so workers wouldn't all be on public transportation at the same time.

Its on a different topic, kinda, but my ex wife had an old aunt that has since passed on that came to Oklahoma before statehood (1907). I think she said she was around seven when she came here. She told of lots of kids dying from 'cholera'. My Mom also told me she had cholera as a child and almost died. Aunt Bess told me she'd lost a child from cholera. She blamed it on the well water they drank. Still, life in those times was an iffy proposition no matter where you lived.
