I grew up in NW Indiana. We are were in the same Chicago's timezone which makes sense, but 20 miles to the south or east of us was on what we affectionately called "Farmer Fuck Up Time". they didn't change for DST. it sucked. hard. I remember calling ahead to ask what time it was when traveling to away games in high school.

Actually Indiana can be used as a test case of how to mess around w/ DST or not. http://en.wikipedia.org/wiki/Time_in_Indiana
