When my kids were younger, we used to take walks to the nearby railroad trestle. It was fun to flatten pennies, hunt for railroad spikes and watch the trains go by. On one of our adventures I snapped this photo of them hanging out as the train rumbled down the line all clickity-clack, clickity-clack.
I recently found the image in use on a Library of the European Parliament website. It’s so much fun to do a web search and turn up my photos in use all around the world.
Here’s a screen capture should the original link be dead.
