I personally quite like daylight saving. I think it works great in California. I remember when it was trialed in Queensland, and I enjoyed it when I lived in Canberra.
I can't remember who told me why the farmers object to it so much, (no, it's not that they're worried about their curtains fading), but it was an interesting explanation:
Farmers work the land, from sunrise to sunset, not the clock. The pub, however still closes at the same time. If they're now knocking off work an hour later, but the pub still closes at the same time, that's an hour less drinking.
No idea how accurate that explanation is, but it makes for a good story.
Anyway, the point of this post is to say that I think the idea of carving the state into two timezones is insane. It should be all or nothing.
