The first time I drove this route was way back in 1966 when I took a summer job in Lewiston and lived in Clarkston. It was an interesting drive for a guy who had never been any further west than Missouri.
Of all the drives I have taken with the motorhome, this one is one of my favorites. As others have said, it is windy and not a road to take if you are looking to make time, but it is a very scenic drive. We were through there a few years ago and got caught in a traffic jam when a semi rolled over. It blocked both lanes so we pulled out the chairs and a table and played cards next to the river. Another guy pulled out a butterfly net and went down next to the river to catch butterflies.
When you get to Clarkston, check out the Granite Lake Campground. It's a very nice campground right on the banks of Granite Lake of the Snake River. If you get a chance, take the jet boat ride up into Hell's Canyon. It's an all day affair but well worth it and a hoot.
