Couple of points.
I've been going up since '94. Back in the 90s, you could hear the fans singing as you approached the ground. For a long time that has not been the case, not just the past few years. Perhaps it was the terracing that made it more atmospheric?
With regards stewards and standing, I have mixed feelings on this. I understand that fans want atmosphere and it's natural to want to stand in this situation, but when you think that kids can't see when everyone stands up it's not really fair. And if your kid is as heavy as mine, you wouldn't be holding him for 90 mins!
And I've been in nasty situations myself, where a group of guys have pushed into my row while every one is standing and then when we're told to sit down there aren't enough seats and it got heated. It's happened a couple of times, once in the east stand and once in the brummie. The one in the east was the worst as we were playing Blues and there were scuffles all around me.
