Love Parade, Berlin
This one is pretty obvious--too many people, not enough spirit, blah blah ad nauseum, as everyone has been saying for the past few years. There are so many people that you feel like you#re in a war zone... it's hazy and smoky everywhere and you can barely hear the techno music, just lots of whistles.
I did go to one of them and it was so crowded that it took me half an hour t oget out and I was almost crushed on a bridge point. It is also notable in that it is one of the biggest and most tasteless ravertrash gatherings in Europe.
Unique Suggestions: The clubs on this weekend have some world class DJs, so i wouldn't advise against partying here during the Love Parade if you already have a place to say. There are alternative parades also going on, and all the visitors in the city give the club scene a nice breath of fresh air.
