Dia de los Muertos has been celebrated in Phoenix for more than 30 years; just ask veteran Chicano artists Zarco Guerrero and Marco Albarran.The holiday's festivities — including the creation and decoration of altars that honor family members and friends who have died as well as processions, prayers, celebrations and gatherings — take place annually in November in family homes and in public gathering spaces. Our must-see: the celebration at the Desert Botanical Garden, where local artists show their ofrendas (or offerings), created to honor and remember friends and family members, to the tune of live music, the annual Procesión, stories and presentations from the artists, and plenty of celebrating. Best of all: There are crafts and authentic food and drink for sale.
