Halloween

Well Mexico kind of did:
" But in 1989 the San Antonio based Gambrinus Group, who were the regional importers of Corona and Grupo Modelo, launched a Cinco de Mayo themed ad encouraging Mexican Americans already celebrating the holiday to make it a priority on this day to drink Mexican beer. The campaign took off.

What occurred in only eight short years was the holiday solidifying itself more as a time to drink Corona than a time to acknowledge the deep connection America and Mexico share. By 1996, consuming Corona as a way to celebrate Cinco de Mayo was the core way most people acknowledged the holiday’s existence, a huge victory for the Corona marketers. That year Gambrinus marketing manager Don Mann said, “Corona is the first thing that comes to mind when customers think Cinco de Mayo.”

However, while I am saddened by the incursion of Halloween into Mexico, I don't think the blame can go to gringos giving out candy. Globalization has made US TV and movies available in Mexico (the Z theater has the same opening date as any US theater) and with that the wide understanding of holidays. And all the stores in Zihuatanejo are full of Halloween costumes and bags to carry to collect candy and downtown all the stores and restaurants have bought there big bags of candy to give out to the increasing swarms of kids in really complicated costumes for, yes, three nights saying Jalaquin with a smile. I don't think, sadly, that today we can turn this back.
