Challenge Cache - A Day of Unknowns Mystery Cache

You've probably heard of a Month of Mysteries. This one is a day of mysteries, or a cache that requires the finder to previously have found an average of one Unknown cache per hour in a calendar day, or a total of at least 24 CACHES OF THIS TYPE FOUND IN A SINGLE CALENDAR DAY before submitting an official "Found" .

This cache is located at the listed coordinates and can be signed at any time. However the cache should not be officially logged as "FOUND" until the qualifications are met (as described above in the "Short Description"); ie, 24 finds of Unknown type caches in a single calendar day . Past finds do count. A number of series that are comprised of Unknown cache types are available to lessen the burden of satisfying the requirements for this challenge, examples being the STS caches (GC418YC) and the A HiDude Christmas (GC1K3CD) series of hides in addition to areas having a high density of Mystery caches, an example being George Bush Park.  When logging your find, please simply list the date for which you made your 24 finds and I will check your qualifications. Logs that are found NOT to meet the cache requirements will be deleted. Parking is near-by.
