I'm an open minded guy who was born and raised in Cologne, studied mechanical engineering at RWTH Aachen (Aix-la-chapelle) . I had 1 year education at the German Patent and Trademark Office and the German Federal Patent Court in Munich to become a German Patent and Trademark Attorney, so I know these cities too, but Cologne I really love and know quiet a lot about what to do and see in Cologne . . . .ask me, if you want ;-)
