My husband and I are flying into Dallas from Sydney in early April for a 3 week road trip, in a Mustang (just in case this matters in regard to road surface). We need to stay in Flagstaff for 4 days, Portland 3 days and San Francisco 2 days. We arrive April 8 and fly out San Fran 29. Would like to have a full day in Dallas so this would require a 2 night stay as we arrive in the afternoon. I would love my husband to see the Airplane graveyard in Tuscan and I would like to see the Morman Tabernacle in Salt Lake City. Any suggestions for a scenic route would be most welcome and advice if all this is manageable.
