Pity the officialdom didnt take a leaf out of the French book!
I am told that noise regulation was introduced in 2007, the entire motorsport brigade said they were not coming out to play, the French then passed an amendment to review the noise levels again in 5 years - everyone is back out playing! - "Vivre la French" sorry my accent is rubbish but I am sure you know what I mean!
We did a hill climb at St Goueno in France last year, key benifits in France are long events, up to 20km in some cases, straight through pipes allowed (pardon encouraged), overtaking allowed (oh er!) definately worth considering for those competing, typically 100 euro entry for a two day event, excellent grub to boot (oh la la!)
Here is a video taken by a very kind competitor who's car went lame.
