Whether or not they let me hang the banner isn't going to make a difference to me. I'll still have it on me. But my main question is do you guys know if there are actually appropriate railings etc. around the ground from which a banner could actually be hung, and if so is that generally ok?
If it can't be hung, so be it. I'll just walk around with it before the game starts - will I have access to walk in front of the Bahrain seating area from where my ticket lets me into?
I'm picking that the atmosphere is going to be fun and sporting rather than hostile so I doubt that I'd cause any great riot.
