Wow. May Day in Berlin is CRAZY! I mean, everyone warned us its a little nuts, but really it exceeded my expectations.
The night before is a huge holiday in Germany as well - Walpurgisnacht. Boxhaganer Platz, just a few blocks from our house, was the sight of some of the major protests/parties here in Berlin and it got pretty crazy. At one point we counted 9 huge Police Vans go down the street, and I didn't get much sleep what with people breaking bottles on my window sill all night.
The next day we headed to Kreuzberg were the big festival was happening for May Day - and it was probably the biggest party just out in the streets I have ever seen. It was a blast!
I can't just choose one photo - here is a slideshow of the whole thing (yeah because after like 2 years of using it I just figured out you can do this with Flickr!):
