Hello, I don't have a acrazy story, but my Germany friends said it was quite an experience, but also said "Make sure to bring a lot of water". there was no love-parade in 2005, but with WM and all, Berline should be a very fun place for this summer!
I found this link that might be useful for some people who don't know what LOVE PARADE is all about.
