No interest in Florida :-) Not that I go down to NYC much these days but have taken the NE Corridor/Acela many times which is a nice enough train ride (and not super-long). Love going in and out of NYC. Taking the train up at tail-end of a May trip from overseas.

Thanks for the info. I'd probably do at least some section of the Empire Builder or Zephyr if I did a long distance run.
