For those of us who saw Mark's post on the train simulator game and thought, "Man, I want that," here's a couple more bits of train-related goodness.
First, back in February, I rode Amtrak's Empire Builder from Seattle to Minneapolis and did my best to live-tweet the whole, multi-day adventure. It's an amazing route, full of buttes, mountains, and some truly dramatic prairie landscapes. This video by YouTube user domtak doesn't quite capture how great the view out the window of the Empire Builder truly is, but it does give you a nice overview of how varied the geography of the United States really is. This 6-minute video covers a whole Portland-to-Minneapolis journey on the train. (With thanks to Thanland!)
