Nurburgring help?

[beej]

How does it work? I've got a few days off next week and me and Mrs Beej would like to do the ring in the cerby.. how do I know if its open? Do I just turn up and buy an entrance ticket? Is it the same rules as a regular trackday - ie just wear a helmet and stay away from Radicals?

Any and all advice is much appreciated. Cheers
