This wherigo cache will take you to the beautiful Furesø lake. Your partner and you must visit at the same time two zones on either side of the lake. Here each of you will find parts of the cache coordinate in encrypted form. Guided by the cartridge, you will input this information into the cartridge, which will then encode the partial coordinate for transmission to your partner.
Upon receiving the partial coordinate from your partner (via phone), you can decode it. Then you can swap the missing parts of the coordinate and race for the cache.
The cartridge is in English only.
Good luck!
