@schm43cky oh I went to Wacken via train! 23 hours straight... left Naples on Sunday at 7am, I was in Hamburg on Monday at 6am. I had my tent and sleeping bag with me + a 45 liters backpack; I bought some canned food in the village.
I think one day I'll try the car experience (must be fun!) but the no-car-area was lovely.
(I went on an Interrail trip after Wacken, that's why I took the train instead of the airplane)
