Headed home through country we have been through several times. Staying in parks we have been in before. Re-seeing sights and sites. Still very fun and beautiful. Not my favorite to do interstates but there are no other options really where we are. If you happen to be in eastern Utah sometime, I heartily recommend I 70. Take it from east to west. Could be done as part of a visit to Moab area. Take Utah 128 northeast from Moab to I 70. Bit of misdirection but outstanding drive along the Colorado river through a spectacular canyon. The drive west to Salina, UT is constantly changing wonderful landscapes. Do it east to west for best views though.
Tomorrow to Ely, NV and the day after to Reno and back into grandparent mode. It has been a great trip. Time to do some catching up and start dreaming on the next one.
