I took a car trip to Żydowo, Poland, a small village famous for its water power plant. From a river three pipes go down to a lake, at the bottom there's the actual power plant.
When you go along the pipes, you can see how huge they are. Adding a person in the photo gives the sense of size.
At the bottom you will find a nice lake, ideal place for summer tanning and swimming. Thanks to the Sigma 10-20 the tree looks really widespread.
