Well, only two of the routes I can count on to be minimal traffic. They are gravel farm roads that aren't shown on normal maps, and unless you are looking for them, you're not even going to know they are there. Much of eastern Washington is desolate, with nothing but large dryland wheat farms (although irrigated vineyards are popping up more and more). The other two routes do require some transit on major thoroughfares, unavoidable I'm afraid. Still, there are detours I can take along these routes if need be.

Ultimately I have to agree that bugging out is kinda like a last desperate act. If things really got that bad, I'd probably only be delaying the inevitable anyways. That's why I don't lose any sleep at night worrying about such things. I've done what I can, and I am as ready as my pocketbook will allow right now.

Now when I get back from Baghdad, that's another story to tell...
