I sent an email to the stadium to clarify
Hi,
I am attending the Speedway Grand Prix tomorrow.
Will I be allowed into the stadium with my camera?
I am a keen amateur photographer.
I do not sell my pictures.
I do not use flash when taking photographs.
Regards,
Andy
The reply
Many Thanks
Unfortunately, camera's are not permitted into the stadium, for further information, please visit our ground rules at www.millenniumstadium.com . We need to make you aware that if caught using your camera, it will be confiscated by one of our safety stewards
