The cows in Indiana are confused enough trying to figure out what a ‘hoosier’ is let alone messing with their times. And they can’t reset their clocks anyhow - their hooves are to big to hold down the little button while they press up or down!
The only thing I really notice is that half the year the radio announcers say the time then say the Ohio time right after. “It’s 8:05, 7:05 in Ohio.” Then for a month after the time change, they say “8:05, 8:05 in Ohio as well.” I’ve lived here 22 years now. Apparently the ‘natives’ are slow learners.
I used to work at a newspaper in North Platte, Nebraska. It’s a town located just east of the Central/Mountain dividing line. The paper, in fact, had a large coverage area that included counties on both sides. We had to be extra careful when it came to calendar listings and such, lest we cause someone to arrive too early or too late to a meeting.
It didn’t really affect my daily life, because I rarely went over to the Mountain side, and when I did, I don’t think it was time-sensitive.
Back in my drinking days I used to go on travel to Yuma, AZ now and then. I would often close up the bars in Yuma (Mountain Time) and then drive a few miles to Winterhaven, CA (Pacific Time) and for another hour.
