I saw some pictures of Wallowa a couple years ago in a magazine, and it made me want to go there. Looks really inviting. If you're going in that direction, I'd say stop in there and see the sights.
Hell's Canyon... meh. Doesn't look exceptional to me from the photos.

Liberty is meaningless where the right to utter one's thoughts and opinions has ceased to exist. That, of all rights, is the dread of tyrants. --Frederick Douglass
