Larry_Parnell If I remember correctly......the neutral area is only pay at the gate, there are no tickets in advance and it is more expensive (£30 I think last year). They don't care where you're from so you don't need any id etc. It's a throwback from when Fulham were in the prem but couldn't fill their ground and was to entice visitors to London who wanted to see a premiership game.
It's actually because there is no way they can safely segregate the area between the turnstiles and back of the stand.
