Many moons ago I taught at Johannes Gutenberg University in the great city of Mainz, Germany--then West Germany. Yes, indeed, that's where Johannes started all this printing business, which is now virtual. Mainz is across the Rhine (or Rhein) from Weisbaden, in Germany's wine country, which is probably still less well known than it should be.
Back then I couldn't have imagined that there would be such a thing as a Poetry Slam in Mainz, chiefly because "poetry slam" wasn't part of the parlance then. I was not aware of a poetry-reading culture in Mainz then, but no doubt one existed. I was just too busy teaching too many classes, improving my German, and making cultural adjustments.
Indeed there is such a thing as . . .
Poetry Slam Mainz
. . .--as well there should be.
