After we'd been married about 5 years, with some rather unpleasant drives from A to B, we got our first dog.
We still didn't stop at interesting tourist points, but "do you think Goldie needs a run?" would fairly instantly get a stop and some fresh air
Now, as long as he knows ahead of time, he will stop anywhere he or I think might be interesting. The lap top has been a great help, knowing ahead of time.
I remember driving by Disneyland, Wax Museum, Knotts Berry Farm
