Last year my family and I went to Durango Colorado (which in itself is not all that exciting, but hey, it was a vacation). If you ever get the chance, go there and take a ride on one of the last steam train lines in the United States. The scenery is spectacular, and the train ride itself is pretty fun.
Here's some of the photos I managed to take during the ride:
This is probably the most visually stunning part of the trip. At a section of rail known as the Highline there is a cut across a cliff for the rail. You can look out the side of the car and see four hundred feet straight down to the river below.
Like I said, it can be a fun experience and one that if you have the time and money you shouldn't pass up.
