Fly to Portland, then get in a car and drive. When you are 200 km from Multonomah Co. and still south of the Columbia, you are getting close.
So where do ya live? 200 km about 120 mi right? that's be somewhere between rufus and arlington?
seen a lot of that area (at about 85mph).
I work on the eastern side from time to time (read as- no work in the valley).
you could be doing a lot worse though, you could be 150+ miles east of portland. where it's not exactly hell but you can see it from there.
the last time I worked over there we had a cinderblock a couple yards from the out-house, with a rope tied to it so you could tie down your lunch-box. that way when you come back out you don't have to drive 2 counties away to pick it back up.
I especially like they way there is no fall or spring up there. summer and winter are divided by a time they lable with those names, but actually they just kinda overlap, with winter at night and summer in the day.
