i was there as well ! and standin at copse... i only live a few mile's away.
that was the busiest i have ever seen silverstone on a tyre test. and also the first time they have charged to get in.

nothin prepare's you for the noise and speed of f1. it's boring on tv but to be there is totally different. much the same as motocross , tv can't do it justice. imo the best motorsport to spectate , by far is pro motocross. if you have never been then check out a maxxis brit championship round or even the mx gp which is held at donington this year.
