Yesterday afternoon, for a family outing, we rode the train from a suburb of Denver to downtown. There are two main lines, both going from south of town to the heart of downtown.
We were hoping to see some Christmas displays in shop windows (like when I was a kid going into Washington, DC). But we were disappointed.
Anyhow, the train ride was fun for all. Very smooth and fast. (Not fast like the European trains, but fast compared enough to be about the same speed as traffic-free driving there.)
Europe does trains right, of course - because they started their networks so much earlier than Denver did. The same goes for many US cities. Now the infrastructure costs so much - but I'm glad they're doing it.
