Agreed, it's also hugely variable. If they've only been once then can they really judge it? E.g. I've seen us play at Elland Road when it's like a morgue, but also when it's rocking.
Terraces were what made me love football, honestly not sure I would have gotten into it otherwise. And I only really caught the tale end of them sadly.
I wasn't born then, but hopefully my forefathers' attendance will be taken into account.
Often still wear my Mets t-shirt which I purchased after a game there for $5 in 2007. Absolute bargain.
