What's the worst crowd surge or crush you have ever been in?

For me it was Anfield in the early 80's. 10'000 Millers in attendance. I was aroundc13 years old. I was stood up in the away section. It was already the fullest away end I had been in when all of a sudden 3 or 4 Millers fans went down with cuts to the head. Liverpool fans outside were throwing stones in. We couldn't move. It was like shooting fish in a barrel. There was a surge and my arm was crushed up against a crash barrier. I was in agony and felt that it was about to break at any moment. All of sudden I was lifted upwards by an absolute giant of a man who stood me on the crash barrier.

I never saw this guy again but he saved me from getting a broken arm and much worse.
