Over the last 30 years there have been five efforts made by eastern Wash. and eastern Oregon to secede from the western parts of their states and join with northern Idaho as a new state (one of the bills -- in 1981, I think it was -- named the new state as the state of "Lincoln").
So, you see, there's precedence. And the Cascade mountains would make for one helluva great defensive position.
Yeah, but can Seattle catapult their cows over that range? I'm sure that they could fart in your general direction. Talk about a nasty Chinook... Well, if rural eastern WA were able to seceed, I'm wondering if Clark(Vancouver, the most conservative part of the Portland metro) and/or Cowlitz County would leave, too. That would give access to the Pacific, no locks on the Columbia south of there. Kinda sticky relying on a river, but its a start. What about Pacific, Wahkiakum, or Gray's Harbor Counties, primarily logger or Native American dominated? Any of those three would provide an excellent harbor location for a base.
