Cache is at posted coordinates.
This challenge is not for everybody. This challenge is for those cachers who like to find more than the traditional green boxes on the map. It takes some real dedication, and maybe a touch of insanity, to achieve this.
To be able to claim a find on this cache, you must have previously found 100 or more of six different cache types (events included.)
For instance: 100 traditionals + 100 multi-caches + 100 mystery caches + 100 virtual caches + 100 earthcaches + 100 events.
In short, if it shows up on the finds side of your profile, and you have at least 100 of it, it counts for this challenge.
Please post a screenshot of your profile with your online log so I can verify your finds.
