Well, one has to wonder about quite a few things, and the seats just one of them. To my recollection, they are quite easy to remove and replace, and in that bulk not too expensive.
What about the CCFC badges and banners?
A new, bigger, better resolution screen. I 'heard' one is due to be installed above Block 34 (the corner of West and North stands). Maybe the one above Block 15 could be made better also?
Decent stadium match clocks. The two TINY ones (one above North block and the other above the corner of South and West blocks) are seriously pathetic. I know there are also sometimes sponsored clocks at the ends of the hoardings as well.
The concrete. The Ricoh is soulless. The flooring should be more like a mall. The walls need to be decorated, maybe some big poster displays, like a Hall of Fame type treatment, maybe celebrating the 150th Year. The various beverage/food stands need to be more welcoming. And has nobody in the UK heard of Turbo taps for beer pouring?
The toilets, especially the ladies ones, need serious work. My daughter says the ones in East Block are the worst she has been to at a big venue (she goes to loads of concerts). Her comment/word was MIRRORS.
... and we still need a stadium name rights deal. I do not think the Ricoh deal brings much in now.
