There are many “Well Rounded Cacher” challenges and it’s quite an accomplishment to qualify for one (or more) of those caches. This challenge isn’t nearly so ambitious but it’s a lot more attainable and it’s really all about the smileys, right?
The rules are simple:
1) You must have found caches with at least 50% of the of the possible Difficulty/Terrain combinations. There are 81 D/T combinations so you must have found a minimum of 41 to qualify for this challenge.
2) Previous finds and archived caches may be used to qualify.
3) Adventure Labs do not count toward this challenge.
