East vs. West

So, there has been an ongoing debate in the Gazette. The debate centers around where should the division for Eastern and Western Montana be. Most people seem to have one of two ideas:

1) The Continental Divide (approximately) should separate the two sides of the state

2) Eastern Montana starts somewhere between Miles City and Glasgow

Personally, I think there should be 4 divisions: Western Montana, North-Central Montana, South-Central Montana, and Eastern Montana.

What do you think?
