Thanks for the replies.
I made the reservation by phone. I was so excited to get someone live yesterday that I forgot to mention the certification expiration message.
I am psyched about our trip. BF and I hardly travel together anywhere except to Sheboygan, WI, and to the NW 'burbs of Chicago. We are visiting relatives in Peoria and Mesa. I also want to see the Grand Canyon--never seen it before.
We are going by train--32 hours from Chicago to Flagstaff. I am looking forward to the train ride going there but I hope I don't go bonkers on the second 32-hour trip back. We will bring books, scrabble, my learning-to-knit materials, music player, snacks, maybe a laptop.
