I am a just few miles south but use the handle ‘Palousex86’ on other forums. Interesting what you say about the terrain challenges...very hilly and irregular contours. I like Dayton area and just to the east and south in Blue Mountains.
When I was a kid, we used to drive between Hayden, Moscow, and Ketchum all the time visiting relatives. Always enjoyed the all-day drive up and down Idaho and going through The Palouse. The highway departments have taken a lot of the fun out of the drives by building superhighways. We drove the old Lewiston Grade last summer for fun. It isn’t called the “Spiral Highway” for nothing!
