This is great information everyone, thank you. We're going to be staying quite close to Newport, so I've put Mo's Newport location and the aquarium on our list. And definitely have set aside at least one day to visit/hike Heceta Head and Devil's Elbow, maybe even keep going to Florence.
Gardyloo, what's the attraction of the OSU campus in Corvallis? Just an interesting campus to visit, or something unusual?
Please keep the ideas coming!
