McMinnville for the best Pinot Noir this side of France. Stop in at Stone Wolf to sample their fine and affordable wines, and be sure to tell Linda and Jessica that Robert said hello.
And the Spruce Goose at the Evergreen Air & Space Museum. Reason enough to plan a trip.
No one mentioned apples, found some arkansas blacks on an old orchard way out in the sticks, was scouting some old places from my boyhood where we hunted and fished the creek, the old homestead had not changed much, the best part is that the apples from all the trees were of the most incredible flavor!! I'll be driving the 180mi next year too, just for the apples..
Summers are moderately warm in the Willamette Valley, but southern and eastern Oregon can get down right hot! I've been in Redmond, when its been over 110!
Don't think anyone has mentioned the Pendleton Roundup yet either.
Don't forget about all the good food thats here too, if you have never had fresh dungeness crab taken right out of the boiler cooled and eaten on the spot well you have never had dungeness crab.And the best smoked salmon you have ever tasted.
