There is a difference between types of behaviour. Personally I have no objection to the music etc, although I think consideration should be given if the vast majority of people on the campsite are in their tents sleeping. What does irritate me is when people return to their tents very late, when everybody is asleep and the site quiet, and then proceed to appear to create as much noise as possible music with music as loud as possible etc.
The other behaviour I don;t like is that which presents a danger to others, this includes some of the antics with fireworks, where for two years in a row I have seen fireworks released inappropriately and have promptly shot through a tent. It also includes those who drive like idiots through a campsite, whether on a motprbike, car, mini-scooter or as I witnessed this year Audi Shuttle vehicle. Those in charge of vehicles should release that many people are wandering around campsites worse for wear and oftn with headphones or ear plugs in!
However in the majority of cases most people attending are considerate, friendly and willing to offer help.
When we got to the campsite the first thing the people opposite did was give us a cold beer, as that was required before putting the tent up. When they realised we hadn;t been to supermarket on the way down, they gave us a crate of beer for the night, and we replaced it once we had been shopping.
Le Mans is an experience and nosie is to be expected.
