I sent an email to the Millennium Stadium today on the subject of airhorns cos one of the stadium rules is that NO fireworks, airhorns(flammable or not) etc are permitted inside, yet as you will know there are dedicated airhorn-free zones on GP day. So what do they expect in the other zones if airhorns are prohibited EVERYWHERE - partypoppers, whoopee cushions, kazoos ??
I bet I don't even get a reply, cos I did "compliment" them on their high standards of organisation !!
