Simple question to ask really, do you want to race on the best tracks in the country, or do you want go a for a weekend away camping!?
We're not blessed in the UK with lots of ideal venues that are all perfect for nationals, so we have to make the best of what we have. If its a choice between racing on a great track (which you can guarantee is what silverstone will provide) or going somewhere like talywain, camping available, but track not so good (those are my kindest words

) then i know what i'd choose.
At the end of the day we go racing to race, not to get drunk or sun it up with our families....i appreciate its not as simple as that for everyone...but hey its 4 out of 6 rounds to count for a reason!
the amount of whining that happened around area 51 and all the doubters....that all got proved wrong by how good area 51 was...maybe you should all have some faith and just get on with it...
On another note, if you want official answers, you should try through official channels, i'm pretty sure oople is not one of them!
