The closest airport to me when I was in Darmstadt was Frankfurt Hahn. Naturally, I had to then visit Frankfurt a few times to get from here to there. Each time, I would try and capture it a little bit more, but this specific time was fairly magical as I had an hour to wander and found such magic as I roamed.
The one punk that I captured saw me shooting at him, and then kept moving to the side to avoid spoiling my photograph!
Also, the girl with her totally rad haircut, she stood next to me just outside the Frankfurt HBF as we waited for a trolly to pass by. I was just standing there ready and it happened. I don’t think she even noticed, headphones and all.
Also, nearly all big-ish (HBF = main) train stations in Germany look like the Frankfurt HBF shown below.
