Interesting! Around the holidays I often wish I could take a train to Chicago or Florida to visit family but coming from California, it is just too far, too long, and too expensive when compared to flying.
Maybe I'll plan a trip to Portland to visit a friend, but that doesn't allow for getting sidetracked and having adventures along the way when driving which is fun when you aren't traveling alone. Plus it's an extra 8 hours by train and seems to be about the same price as a plane ticket. I suppose it would be an interesting experience though.
