I've seen far more phone videos from the east and west stands than I have form the North to be fair!
I think the west upper must smuggle in their camera kits (and coffee flasks) under their blankets!
Are you in the North Marc? Most in the North get a better view looking at the screen behind them than the screen on the other side of the pitch. And sometimes people like to see the replays that are shown after the event, even if it has just played out in front of them. Have you never watched...
