Volker - You are now on the map, basically in the BMW building I was in a few years ago.
We were there in late September for a "small" celebration with a parade, some tents in a large field, and lots of singing going on in the Hofbräuhaus.
Unfortunately we planned to visit the BMW Museum on Monday, obviously unaware that museums are closed on Mondays in Germany. But we did tour BMW Welt, got our pictures taken with the car and bike used in a movie, the BMW Isetta, etc.
As for Bayreuth, I haven't been but know where it is. That's because we know some people named Bayreuth here in our town and that's where they are from so I looked it up. Probably the closest I've been is Nuremberg.
