Thanks for all the help, I was hoping that the bus would follow the 285 for all or some of the way between Albuquerque and Denver, maybe to serve smaller communities away from rail track and the Interstate. Now see that it largely follows the SWC track. What puzzled me is the route of the 8804 bus in the separate route/schedule Thruway panels was not listed as leaving Albuquerque, it was only shown as leaving Raton, although it is a separate listed Albuquerque service when buying a ticket.
Bus travel... we're all different and appreciate different things in life, on top of which trains in almost any country don't go to all the places we wish to travel to. I do remember on the very first very long distance Greyhound taken years ago we stopped at a crossroads somewhere in N Dakota , there were 4 buildings one on each corner and that was it as far as the eye could see. It was February, pretty bleak weather wise.
When we de-bussed I was amazed that the café was pretty full already, we were the only bus at the stop. It took a while to realise that the Greyhound stop was the center of the unseen community and this small café was their meeting place. Having grown up in a mega city it was about as opposite to my life as possible and has stuck in my mind ever since.
That 7 day bus ride was the first time I (Rosie wasn't on the Greyhound part of the journey, we met up at the end of it in Phoenix) started to really see America and it's people, the good, bad and the ugly. We had taken at least 5 or 6 US fly drive vacations previous to this covering thousands of miles each time, but that week was a real eye opener.
The inspiration for that first Greyhound ride came from a book called 'The Great American Bus Ride' by Irma Kurtz. She went on a gruelling 3 months Greyhound trip and explains far better than I the allure of sometimes travelling Greyhound. Worth reading to the end as you understand more as to 'the why' the longer her trip lasts.
Thanks again for the comments, it all helps.
DA, southern Germany by road in particular the Deutsche Alpenstrasse is exactly as you write, spectacular. My opinion is the very best way to see that and the eastern side of Bavaria is with a camper, slowly.
