We did that trip 2 years ago. We left Aug.14th and got back home on Oct. 1st.Started out Mo. to MN., then to ND through MT. On to ID , to Columbia Gorge, then to Astoria and down the coast, last stop Bandon. We stay 4 places on the coast so we could explore in 50 mile radius. then we went to CA, and headed over to Carson City, left there and traveled RT 50 across NV, and took 80 to Iowa and went south, home. Could have done more sightseeing in NV, and took on CO but was homesick by that point. Beautiful scenery, a trip to remember.
