Leaving at the end of May and looking for any suggestions anyone might want to share. We start in N Orleans, to Austin, Carlsbad Caverns, Santa Fe, Mesa Verde, Monument Valley, Grand Canyon, Las Vegas, Death VAlley, Yosemite then on to Portland. Looks like the National Park tour of the Southwest! We have some reservations at heavily traveled locations - Grand Canyon, Death Valley and Yosemite but looking for suggestions for scenic drives and not to be missed sights. Any and all suggestions gladly accepted!
