It’s actually the LAST day of Dia de los Muertos for this year. This is the Mexican holiday that pays respect to past ancestors. There is much more to it than that, but that is the basics for anyone wondering what this is about. There are lots of celebrations and many people that participate in it. I have a few Mexican friends celebrate this day for more religious reasons while others that celebrate it for party reasons.
