 GEOG: When the family is "driving towards LA" there is a shot of  them driving under a maze of tan freeway overpasses. It is obvious  that this is an Arizona freeway (all the nicely landscaped tan rocks  with perfectly placed desert bushes gives it away). In fact, this  section of freeway with the overpasses is actually US 60 eastbound  just east of Phoenix in Mesa Arziona near the Superstition  Mountains.
