Ok, for this Christmas we are going out to Grand Junction. Why? Because I was bad my wife's parents live out there. So I figure, let's take the train. 8 hours on a train sounds better that 8 hours in a car. Yes it costs more than driving (5 of us round trip is $440.00) but still, more comfortable and less carbon than driving.
And they're sold out. It's understandable as Christmas has to be a very busy time for any transportation. And it does not make sense to have additional trains that run just a couple of weeks a year. But it is also a reason that many times our car remains our only alternative.
