I'm french! And believe me, La Tour de Scay is nothing near Buthiers in terms of riding spot! Also, there is absolutely no organization possible there for people who want to camp! Last year at another comp, two bike were stolen at La Tour de Scay... end of story!
Just don't go to Koxx Days, to show them that trials has to rely as an important thing for koxx! They have been caring too much for BMX, scooter riding and other stuff...
