I spent several years flying around Oregon, Idaho, Washington, Montana.
The Dalles airport cafe is a good lunch spot as well.
Take yer girl friend to Trout Lake, WA. for a weekend get-a-way....the Trout Lake Motel is a very nice place with really friendly owners.
After the snow melts on Baby Shoe Pass....take the 23 road to Randle, WA. and take in the Steam Train at Elbe and drive on up to Mt. Rainer.
