The Ricoh is a nice stadium and if it was CCFC's stadium and we were in the Prem it would be nice. At the minute it is an empty football stadium so why would I be too fussed about it? I don't see the reason to go there without the football unless it's a gig that happens once every so often or the casino for the odd beer.
I'm not doubting it is a nice stadium but so is the San Siro or the Nou Camp (not that I am saying they are on the same level) but CCFC don't play there due to a mixture of SISU and ACL's mess.
The Ricoh isn't the "heart" of a community, if it had a training pitch for example where they had kid's coaching and summer play schemes and things like that which made people go there then it would be different. You say that you only see bad in SISU and good in the Ricoh, you are blinded by hatred and that is not me saying "everybody must love SISU and be Tim Fisher's best friend".
If CCFC aren't there then most have no reason to go there but I am not sure how you can "support" a football stadium?
