August, 2013 was designated as the "31 Days of Geocaching." Cachers earned a souvenir for each day in August that they logged a find or attended on a geocache.
To celebrate the "31 days of Geocaching," a series of "31 Days of Flashing Cincinnati" flash mob events were held. Several of these events were held very near this cache, at 6:30 PM on various evenings.
This cache commemorates these events.
