Great trip Peter. We went from Chicago to Santa Monica in May of this year and know all the spots you mentioned. The weather was much nicer than what you had to handle. 3 couples driving a '62 Stude wagon, a 1956 Chev sedan and my 1965 Malibu. But all were V8 cars. Doing that with your grandfather will be a lifelong memory. So glad the car worked real good for you.
