Edge Loves Series are meant to create high Difficulty and Terrain cache in urban area, please bring your own pen.
High Difficulty comes from quiz-like puzzle, the answer would be one word or several without space, all are English letters don't bother to try number or symbol. At beginning there won't be any hint, but more hints would be added every week until the checker show someone was certified.
High Terrain is because you just can't grab the container by hands, just like other high terrain caches like climbing or diving it need special equipments to reach out for the cache, figuring out what to use is the challenge, don't put yourself in danger!
Geocacher who found the cache must leave the signature, if CO doesn't see the actual signature, the log would be deleted without further notice.
In Taiwan there are many caches still waiting for FTFs, CO feels annoyed for those and decides to make own annoying caches, just like the cache's name it's personal. Also delighted not have to go to high mountain or deep water for making the series.
