I've seen quite a few challenges and points of pride over my geocaching career. Find one in every county in a state, find one in every state, find one on each calendar day, find one placed on each calendar day, find 100+ caches in a day, discover or move N number of travel bugs, complete the difficulty/terrain matrix...
This cache won't help with many of those challenges. It will help with one of the more difficult challenges (to my mind) though, the streak. This takes time and dedication. Planning what caches to hit on what days and not clearing out any given area too quickly. To those working on a streak, this one is for you.
