I started in New England, went over to Chicago, down to Austin, and then spent weeks going from Austin to LA to San Francisco to Portland and finally to Seattle. It was one of the greatest trips ever. I took the train you were talking about with the observation room, and had one of the best dinners of my life with 3 other strangers in the dining car (all of us were traveling alone, and they seat singles together at one table). Three of us were young college kids, and then an older gentleman. We talked for hours- about youth, the world, everything.
