Tricerahops is a notable, hoppy beer you can get up there. Anything by Deschutes will be great. Try to get their new 'Hop In The Dark'. Fresh Widmer beers can also be great examples of American wheat beers.
A surprisingly good beer is the 'Black Cherry Stout' by Walking Man out of Washington. IMO one of the best implementations of the combination of cherries in stout.
I second Pliny the Elder and especially Blind Pig by Russian River. Both are most excellent.
If anyone happens to be in the Portland area, a stop by Belmont Station bottle shop (http://belmont-station.com/) and the Horse Brass pub (http://www.horsebrass.com/) are most highly recommended. They are only 2 blocks apart.
Just a few thoughts off the top of my head.
