Trek places in Germany?

[rag]

As I'm visiting Germany (the-most-Trek-friendly-country-in-Europe) next week, I'd like to ask for recommendations of any interesting Trek places there. Bookshops, full of new and old Trek books; shops with Trek uniforms, communicators and Vulcan teddy bears; Star-Trek-Experience-likes; etc.
And close to Karlsruhe, if possible, but not neccessary.

(And yes, I really believe that Germany is the next best Trek bonanza, shouldn't I? ;) )

I don't know about anything Star Trek in or around Karlsruhe, but I consider the area of Baden-Wurttemberg to be one of the two most beautiful places in Germany.

Rich in history, I would love to be able to spend just one day there. Should you get the chance visit castle Hohenzollern.

Edit: oooh, I just noticed your location listing. Cracow, also very rich in history. . .another place I would love to visit. I would love to see Rynek Glowny (sorry if not spelled correctly).
