We did a similar trip way back in the dark ages when our kids were small. South to LV, across Arizona, seeing the Grand Canyon, Petrified Forest, etc., and on to New Mexico through Albuquerque, then north. We hit Denver and then headed to Yellowstone and back to Lake Tahoe and home.
Every zoo that was possible to see was on our itinerary. Our kids loved zoos, and even as adults they go to the zoo in new cities. The one that stands out in my mind over 40 years later is Denver, where we saw a deer giving birth to triplets. ABQ and Colorado Springs were also memorable ones.
