Driving a car out to LA around the end of August so we're looking to have fun along the way. Not in a hurry. Planned stops to visit friends and family and general sightseeing include: NYC, DC, Nashville, New Orleans, Dallas, Santa Fe, Grand Canyon / Scottsdale, potentially Vegas then on into LA. What are we missing in this itinerary? We are not in a hurry so we have some time to explore. Thanks for your advice.
