I've been looking into it more, but you know how we are over here. Gotta take a 5 day train to get from DC to Chicago, than another 5 days from Chicago to Nashville XD I'm exaggerating slightly for effect but I think you got it.

Earlier this year I quoted an amtrac trip around the us, hitting major cities, and I think the full round trip, if you didn't get off the train was still over 2 weeks.
