Döner's Tag 2017 Mystery Cache

In 2007, A Geocacher in Berlin, Germany started an anual Geocaching Event that happened all over
the country, and always on a Thursday. This Cacher had 595 atendees! at his first Doners Day Event.

10 years later Groundspeak decided to make it Worlwide Event
and offer a New Souvenir for attending a Dönerstag Event on April 13, 2017.

In Honor of Dönerstag 2017, here is a Puzzle Cache for you to chew on
