You’ve probably seen sugar skulls. You must have watched the movie “Coco”.

Dia de los Muertos is a popular holiday in Arizona, and indeed everywhere else, but it’s also a holiday that most of those who celebrate it don’t know much about. And while there’s technically no wrong way to celebrate, there’s definitely a right way.

So how do you celebrate Dia de los Muertos respectfully?

We find out this week in the Valley 101 podcast from The Arizona Republic and azcentral.com. I spoke with Arizona State University professor and vacation expert Mathew Sandoval, as well as Republic reporter Tiffany Acosta, who has written extensively on this subject. And yes, they’re both talking about “Coco,” which plays a bigger role in Dia del los Muertos than you might think. It was a very lively discussion and I learned a lot. You could be too.
