HI Chaz, I'm from Bayreuth, but I'm afraid Wagner isn't exactly my cup of tea.....
I had tickets for Parifal in August, but no one was willing to join me etc, so I gave the tickets to my friend + husband ;-)
I think it was the fault of the Wagner-familiy, especially Winifreds, why Wagner is still linked to anti-semitism.
But nevertheless, Bayreuth is worth a visit, even in the rest of year, when no Wagner-related events are.

I would write this in german ,but would make a fool of myself mein Deutsch ist schlecht. But since you live Bayreuth I wanted ask if you like Wagner as much as I do. This is a little embarssing, since Richard Wagner has so often been linked to anti-semitisim, but I think the only Opfer may Meistersingers where any thing like that may occur.
