You wouldn't think it to be a BHA exclusive area though - the club have made it abundantly clear that the 1901 club permits, nay encourages, the use of tickets for hospitality purposes and, as such, there is always the chance of opposing supporters being present there.
Again, in most stadia...
Nope. I didn't know (or don't remember why) it was closed. However, I can assure you that I don't censor discussion because the club have asked me to do so.
Do you have a link to it?
