> Editor’s note: This article has been retracted as it does not meet Atlas Obscura’s editorial standards. Our investigation revealed the author fabricated interviews with at least one source; Brian Akers confirmed via email that he was initially contacted but never interviewed by the writer, and that quotes and other material attributed to them by the writer have been fabricated. Giorgio Samorini did not reply to multiple email requests for comment. Jitka Soukopova confirmed via email that she had been interviewed by the writer and material attributed to her was accurate. Additional details provided by the writer could not be verified.
