Well I do believe them. But at the same time they have to say what they have to say. They said there were no plans for expansion less than a year before adding a second tier to the East Stand, I believe.
I think this only applies to the east and west stands but could be wrong. I've been trying to look at Jack Straw's photos to see this, but can't find one from the right angle.

I actually agree. I think there's still a hell of a lot of untapped support in Sussex that could be encouraged along, but it's likely to be prohibitively expensive.
