Under the heading safety; Citation: The following objects are strictly prohibited: - plastic bottles, camelbags, canisters and drinking horns. Please note that W:O:A festival cups and the foldable bottle you get with the FMB are allowed. Unter sicherheit; Zitat: Folgende Gegenstände sind verboten: - Plastikflaschen, Camelbags (sog. Trinkrucksäcke), Kanister und Trinkhörner (W:O:A-Festivalbecher und die faltbare W:O:A Wasserflasche sind erlaubt) Why Ban rucksac carried water bags? It is soft, contained in a rucksac and is vital for some to have a safe easy to carry water store. Namely like my son, an asthmatic, who must keep his hydration up at good levels... but no, he must run about with a 40 or 50cl plastic cup and get water from a wash area... or pay stupid money for bottled water from the vendors! Water is life, not profit or a security/safety problem! I can just see him getting annoyed about something and bending down to pull out his water bladder, unhook the drinking tube and throw it 50 mtr to the stage... Lach mich kaput!
