There were two huge GA queues. One of them started right in front of a gate, the other at a bizarre and apparently pointless fench on the pavement 100 yards from the gate.
When the gate for the first queue opened there was the usual huge rush forward, quite a few people jumped the barriers into it, and others ran forward. There was a bit of anarchy for about thirty seconds as the security lost control of it. And the other GA queue hadn't even moved at all about *thirty* mins later. The people at the front of it may well have been shafted - but as I wasn't in it I may well have missed where they were directed to go on the field once they got in.
