Been there yesterday, the whole thing was crowded with about 500k people. Haven't seen much of the game (I'm rather small) and beer was expensive. Still that was some crazy event.
Had to keep my sympathy for England for myself as luck was with me and I stood next to the only larger (~15 person) group of Neo-Nazis that was there. :( Oh my. Funny thing was that they applauded the goals of Polish and Turkish players. Hehe.
