You know it's going to be a dry site, right? No beer.
Some of the stuff that has gone on at the "official" Inters camp sites in the past has been shocking: 4am drunken rally driving with cars getting smashed up, tent destroying, as many brawls as you can shake a stick at.. you get the picture.
Think about it from the organisers point of view. There's an old airstrip with miles of flat de-restricted tarmac, hundreds of brand new cars in storage (with the keys in), loads of old planes and acres and acres of land to Police.... and a load of drunken people = temptation for a small minority to ruin it for all.
I think (unless there's been some serious negatiation) there's going to be some very unpopular rules. Like not being able to take cars near the camping area, no drinking, no BBQs etc. - I know from organising the last 3 stands for MKIVs, the list of things banned from site for insurance reasons reads like War and Peace!
