Here's a regular 8mm home movie from 1963 showing a road trip through New Mexico, Arizona, and southern California -- the southwestern states of the US -- though the focus is mostly on Arizona. 

A few things shown include the sign “PETRIFIED FOREST NATIONAL PARK,” POV driving shots of Arizona desert landscapes and roadside homes/shacks, the sign “ARIZONA COURTESY AND INSPECTION STATION,” various petrified wooden logs scattered throughout a desert area, a man lighting his cigarette while leaning against his parked car, the sign “ HASTA LUEGO DRIVE SAFELY,” and the sign “CALIFORNIA STATE LINE.”
