Some of my readers will remember Freiburg's Wagenburgler Story. Over the last years it has become quiet around the groups who like to live in caravans. They were roaming Freiburg in the years 2011 to 2014 for a site to park their vehicles in the shadow (Schattenparker is the name of one "tribe"). Another group calls itself Sand im Getriebe (sand in the transmission) and indeed the quarrel with the city went "vicious" until most Wagenburgler had found their rest at a site near Freiburg's airport called Eselswinkel.
They are planning their yearly Diesel’n’Dust-Fest for September 15 into September 16. Mind you, #Dieselskandal is not such a dragging name presently.
