*The reference coordinates are not to be used as the cache is NOT hidden there*
As the number 5 is a lucky number for me, I noticed the date was the 5th of the 5th so I created a cache without really knowing what to call it. I then discovered that it was a special day in its own right and was known throughout the world as Cinco de Mayo.
Cinco de Mayo—or the Fifth of May—is a holiday that celebrates the date of the Mexican army’s 1862 victory over France at the Battle of Puebla during the Franco-Mexican War (1861-1867).
All answers feature the 5th of May in one format or another, but you will have to discover the ‘Cinco’ year to obtain the coordinates.
