Garry, you're trip sounds fantastic. We're going from LA to Emeryville on the CS, then on to Chicago this month, laying over in San Luis Obispo so we can go to the Hearst Mansion again at San Simeon. I'll post about our journey as we progress.
I'm a newbie also although I've travelled by train my entire life. Living in Florida is certainly flat so I am looking forward to the Coast Starlight and Cal Zephyr this month. May should be a nice time of year to visit the States also.
I'm glad you "much preferred the scenery on the CZ, including the "boring cornfields"" because I too was trying to decide between the CZ and EB. I just booked the CZ for my wife and I in late October. After reading this thread I was beginning to doubt my choice. I know they are both beautiful...
