"If at first you don't secede..."

Somebody asked about a secessionist movement in Montana. Can't find anything specific, but a post in a discussion forum of the Sierra Times gives a good run-down on such movements around the country, along with some constitutional basis thereof.

It seems there's more to this than a few crazy guys with gun racks.

(Update: More information on secessionist movements in various states can be found at the website for the American Secession Project.)
