M.hony,
My husband found the book through the online book service--can't think of the name--"senior moment" here!
Just put out a search for it and it will come through eventually. I really enjoyed the book, it is a completely different story than the movie; I'm sure you will get a real kick out of it since some of the problems of trailering in the days it was written are very different from ours today, but also some are very much the same.
Now that you've reminded me, I'm going to read it again.
