While not technically a road trip, I've got a trip coming up at the end of May to Moscow, Idaho. I'll be flying in to Spokane and will have a couple of days to poke around after I take care of some work related activities. The last time I was in the area, I made the mistake of driving through at night and I intend to rectify that this time. The area I'd like to explore is bounded roughly by Spokane and Coeur d'Alene on the north and Clarkston and Lewiston on the south. I'm mostly interested in geology, history and one-of-a-kind oddities along with, of course, a preference for the scenic byway over the interstate. Any pointers to such things in the area, or even your favorite cuisine would be appreciated.
