"clever outdoor art installation: that’s what most passersby will think as they pass GZ. Little do they know, one of these bottles is not like the others. Thanks to the custom label, geocachers should be able to locate the correct bottle easily enough. Uncorking this cache will be a whole other challenge, though. Those who partake in puzzles will know to check the cache page to decant the mystery of this cache."
