straight from the Thursday press conference (transcript at http://www.autosport.com/news/report.php/id/59115 ):
Q. (Fredrik Af Petersens – Honorary Media Pass) Question for Ron Dennis: why isn't it allowed to read the Red Bulletin in the Communications Centre?
RD: Well, I think it's a piece of rubbish. I feel that if we all focused on humorous magazines that criticise the other teams, I think the likes of Ferrari, with the support of Marlboro, could spend a lot of time and energy writing humorous things about other teams and individuals within the sport. I have a simple view that if people want to come and enjoy the hospitality of McLaren, then they should respect the fact that I don't particularly like what I consider to be a controversial document coming into our facility.
They can go and sit in Red Bull and eat to their heart's content and enjoy their hospitality. But I don't like it, I don't like what it stands for, I don't like the quality of it, and I don't like the way it tries to make fun out of individuals from every team and their efforts to try and do a good job. So I think that's a pretty straightforward answer and leaves you in no doubt about my feelings. I don't think it has a place in Grand Prix racing.
