Bill, One of the most basic reasons that Northwest Indiana is in the same Time Zone with Chicago is because so many residents who live in Indiana work in Chicago. This can be accomplished with only a 45 minute commute each way. Could you imagine what it would be like if you (theoretically) had to change your watch every day as you were driving to work and then again when you were driving home??
To add a little more complexity to Time Zone Plan. There are areas on the other side of the planet that have Half-hour Time Zones.
Actually, on this side of the globe, There is Newfoundland, which as 1/2 Hr off Atlantic.
Howewvet there is some counties in the mideast with a 15 minute offset.
In Canada Saskatchewan is always on the same time, the result being in the winter, I get 5 time zone feeds of CBC on satellite. in the summer, the Regina CBC is on the same zone as one of the other cities, knocking me down to four Time zones of CBC to choose form.
Pearlfish, There are a lot of people who live in Richmond and work in Ohio who deal with the DST difference every summer. I just wish Indiana was uniform with their time zone.
Fred, it sounds like the folks in Richmond need to slip fatter envelopes to their politicians. If you hold more voter registration drives in your local cemetaries like we do, you might not have those problems.
