Remember there was a big fan park near the ground on the old brewery site. More in there than the ground I think.
The teams based up here didn't help, it's not like Bulgaria and Romania had 1000s of fans flooding into the city making a party atmosphere. (If you read mbh's post on the politics forum you would think every city was flooded with them)
It just never really caught the imagination in the the city, don't know anyone that went. I think these days it would sell out.
The rugby World Cup games sold out up here easily enough.
Olynpic football was sold out for all the games as well at st james. Although having Spain and Brazil with young Neymar probably helped
