Thanks for linking/posting your pics. I'm doing the Builder west-east soon, and it was nice to view in advance some of the sights I'll be seeing. A question for anybody: How's the ride in a lower-level roomette? Never had one before (but do this time), and I guess the closest thing I've experienced was a Viewliner room. Previously I've only used the lower level for a shower (while stopped), exiting for a smoke, and briefly for photography.
Also, in one pic caption, "Community" was an interesting way to describe the dining car arrangements. I call it eating with strangers, but either way it's fine with me. Only one bad time, when an older couple said not a word to me or each other, and only talked when ordering (Silver Meteor, D.C. to Jacksonville). After that awkward experience I always take a book to the dining car, just in case.
