This sequence of month, date, and year (12-13-14) will not happen again for about 1000 more years, sometime in the year 3000, like January 1, 3001, so it needs to be commemerated in geocaching history. Asked geocaching.com if they were going to do a souvenir for this unique date--after all they did for 12-12-12), but they said they were not going to do so; thus I made a cache to commemerate this date.
