Thanks for the replies, and sorry for the silence since posting, work got crazy and travel plans have shuffled.
Still heading to Music City the end of the week, though need to leave sooner than I would have liked, so we only have one day semi-free.
Larry, I'm hoping to be back in the fall, home layouts are always interesting as I've run a few tours in Boston's southern suburbs. I see there are a couple of museums with 1:1 trains I may have time heck out this trip. Though, another New England winter like 2015, and I just may be coming down for good!
Chuck, yes I've been to the Union Station, beautiful. Though a round of drinks at the bar set me back about one diesel engine. Took this shot outside my hotel window when we ewer there a year ago...
