Today is Cinco de Mayo, a Mexican holiday. What do we know of this holiday? TV ads show people partying and drinking beer. One beer company makes a big deal out of the holiday. Thankfully, because of the Internet (and not what I learned in history classes), I now know that Cinco de Mayo commemorates a victory by Mexican troops over the French in La Batalla de Puebla (Battle of Puebla, Mexico) on May 5, 1862.
Viva la Mexico!
