This year, my wife and I took a three week trip out west. We took the train for most of the way and it was fun. I enjoyed being able to look out the windows at the scenery without having to worry about the road ahead of me. One thing that did bother me a little was that there were so many times when I would have liked to have stopped and gotten a closer look at something and perhaps take some pictures.
We took thousands of pictures and I have over 600 posted on Flickr. I won't post that many on here, but I wanted to mention some of the problems of taking photos from a moving train. Focusing is impossible. If nothing else, the foreground will always be blurry. While shooting through windows, you have to deal with reflections, glare, tinting, dirt. Most importantly, you only get one chance because the train just keeps on moving down the line.
