>I'm not entirely sure, but I thought the entire state was technically supposed to be in the eastern zone. The problem, I think, is that the western part of the state is so far west in the eastern time zone that it's effectively central time, that is, running on eastern time in EDT, for example, would give very late dark mornings even in summer. Thus some localities opted out of the state standard...

Must be damn confusing if you go for a walk and accidentally cross the line!!!
