Obviously you didn't pay much attention to the wall at the back of the Pop Side because there was a gap between the wall and the roof....admittedly not a massive one but it didn't go right up to the roof.....
As for the distance between the action and the supporters seeming so far away compared to KR...are you being serious ??? Maybe your eyesight has deteriorated in the last couple of years but to suggest that has affected the atmosphere is almost laughable
