I took those at the local oil harbour in Bavaria, Germany.
Was quite funny, because all of a sudden a group of workers appeard, walking toward me and looking angy. Turned out they were interested and friendly and told me that there were one or to photographers checking out the site everyday .
Your pics tend to have a slight tilt to the left, do you see that?
My favourite of these four is the third, the close-up on the crane compartment. But there's no one in there! Ah, sure, he was coming up upon you with a sour face, too, right . You were lucky there were friendly, after all!
