Oh don't get me wrong, they were great. In general, the Germans were great hosts. I didn't encounter any hostility towards Americans (as was definitely present in some of the other places ive been to...) or any poor service at all. Aside from some serious organizational fuck-ups in Dortmund (they were still learning, it was their first game there), everything was perfect.
Thumbs up to the Germans, if only FIFA could've sorted out the refs
