John,
I have to agree it had some unforgettable road scenes. I only saw it when it first came in Auckland after staying at Felix St. Whenever I drive into LA on Pacific Coast Highway I think of the scenes filmed there. Here is a site that shows where most of it was filmed and I have driven through each place except for the Florida scenes. You must put it on your "Bucket List." That will be on your way to drop in to visit us here in Los Olivos.

I also liked the movie "Vanishing Point" with actor Barry Newman and Gilda Texter riding on the motorbike ! That is what lured me to the states after I watched it in Hamilton in 1971.
