47 years ago, I road in the back seat of a Plymouth Fury III from the Philly area to Palmer, AK (north of Anchorage). Many stops in the mid west thru Canada. Stayed with relatives in AK. Did trips to Anchorage, Homer, Denali (Mt. McKinley at the time), and Fairbanks.
We flew home (my first airline flight - Northwest Orient 747). Other relatives flew to AK to drive the car home.
