I went last year, and before that at Donington, but to be hones I hate Silverstone almost as much as I hate getting to Silverstone, so didn't bother this year. If they take it back to Donington I'll be there.
I went yesterday and thoroughly enjoyed it, none of the forecast rain and the satnag took me round most of the traffic, especially coming out.
We spent a lot of time at Abbey so that SWMBO (Who'd never been to a race track before) could get a good look at the cars as they slowed. Cracking day out for only the cost of the petrol.
