This is a photo of a typical May Day celebration in Kreuzberg, a quarter of Berlin sometimes abbreviated X-Burg, sometimes XB, and sometimes &amp;#8220;,&amp;#8221; (a single comma.)
XB is distinguished by its low-lying fog, which fills the streets from March through June most years and is called Batteriegestank as it smells of alkaline batteries.
