I would have to say that so far the two most scenic parts of the road trip have been from Crater Lake to Salem, OR last Saturday, Aug 22 and Portland, OR to Heyburn State Park, ID today. Driving along the Columbia River Gorge which slices through the Cascade mountain range was pretty spectacular. The cliffs on either side of the river were quite dramatic. It was almost as if someone took an axe and chopped shelves into the side of the mountains on either side. Although it was overcast and drizzly for the first part, the sun did come out and I was able to pull over into a state park and grab some photos from the bank of the river. The wind through here is no joke which is why it's one of the hottest windsurfing spots in the U.S. Once I crossed the river and entered Washington - I hit probably the least scenic part of the trip - mucho farmland.
