a cordoned off area means its SANCTIONED and as such will require marshals, site permissions, accident cover in insurance and paramedic personel, and someone to pay for it all.... why do you think it HAD to stop at the Nats, and doesn't happen anywhere apart from racetracks????
you've been told this already and you still don't get it.
Guildford was killed by boy racer twats, Lakeside the same, and it's going so well for the Ace cafe at the moment with burnouts and idiots!
if you can't get it into your head that burnouts have SPECIFICALLY been asked to stop at dockside by the owners of the site, then you can sod off and join the children crashing at Medway city estate.... oh.. with the anti social behavior dispersal zone in force there you can't can you....
