When Wayne is holding the envelope which contains his learners permit, you can see the address reads California. The writers always said they wouldn't let the audience know where the Arnolds lived so people could relate to them better. Wayne should have been covering up the state and first few numbers of the zipcode. Another thing...didn't they just drive to Ocean City (NJ or MD?) a few episodes earlier? That's a long way from California!
Narrator: As we drove home in silence... we began to realize the absurdity of our situation. We were two people, with almost nothing in common... thrown together by circumstance. The harder we struggled against that fact, the more tightly we were bound together. That night, the gap between thirteen and sixteen... got a little smaller. I didn't make it back to the mall for several weeks. Somehow I just didn't feel like gettin' in a car. As for Wayne and me... we'd reached a new understanding. We didn't have to be friends or anything. But we'd always be brothers.
Narrator: Once upon a time, I lived in a great big house. With a great big yard, and a great big bedroom. And a great big older brother. But by the middle of nineteen-sixty-nine, the house and the yard and the bedroom were are all getting... smaller. Or maybe Wayne and I were getting larger. One thing was certain. We were running out of room. The pressure was building. Then, just when things seemed near the point of no return... something happened. Something unexpected. Something... terrifying.
Part of this episode was filmed on location in Downey, California at Stonewood Center. This was one of the last outdoor shopping malls in Southern California before it was converted to an indoor mall to keep up with the times. The mall provided the feel of the 60's for the time frame that the show was set in.
