We stayed at the aire in Catillon-sur-Sambre in June 2008. At 11-45pm four drunken youths turned up, unplugging a german vans hookup.Then using his lead to power a ghetto blaster blaring rap music. They sat on the picnic bench drinking whisky. After this the four of them pushed two large boulders into the canal. They then climbed into the building site behind stealing two wooden pallets which they placed against the rubbish bin and set fire to the lot. At 2am they left shouting English out and Bosh out only to return minutes later throwing stones at our vans from the bridge and the other side of the canal. An English man confronted them only to have CS gas sprayed into his eyes All four vans then left under a barrage of stones. Two of us stayed on a lorry park 3kms down the road for the remainder of the night. In the morning we reported the incident to the town hall and the local police.
Great to see that you are taking a sensible approach,that you can see it for what it is a very isolated and uncommon incident and that it will not put you off Aires in the future. Tens of thousands of good nights sleep are had on Aires every year, its an excellent system that we in the UK are rightly jealous of.
