This year's parade features two grand marshals, 64 parade entries, 10 decorated floats, music, food and more, all relating to the 2013 May Fete theme, "What will you discover?"
The theme's diverse nature — fostering exploration, curiosity and discovery — led to having two instead of one grand marshals, said Alison Williams, the event coordinator.
The grand marshals this year will be block preparedness coordinators from the Community Emergency Response Team and a representative from the Cantor Arts Center.
"We've gone from science and helping the community to art programs," Williams said. "It's so diverse and different, showing how many things are out there to discover."
Williams said that participants include numerous preschools, elementary schools, Boy and Girl Scouts troops and organizations such as the Palo Alto Humane Society and the YMCA.
Entertainment will feature clowns, seven bands — one of which will be the Stanford Marching Band — and dance groups from Dance Connection.
Though the parade ends at Heritage Park on 300 Homer Ave., the celebration continues with the May Fete Fair.
The fair will feature 29 booths hosted by local businesses and nonprofits, such as the Palo Alto History Museum, Galileo Camps, TheatreWorks, Magical Bridge and Zero Waste Palo Alto. The band Grounds for Dismissal, Palo Alto school bands and the Stanford Marching Band will all perform.
Several food trucks — Armadillo Willys, Kara's Cupcakes, MoBowl, The Mulberry Guy and WeSushi — will serve food, according to the fair's Facebook page.
The Museum of American Heritage, across the street from the park, will have antique cars parked on the street, as well as a museum exhibit and a family fair as part of its Annual Vintage Vehicle and Family Festival from 10 a.m. to 2:30 p.m.
May Fete, the oldest children's parade in Northern California, is sponsored by University Art, Palo Alto Toy and Sport, Stanford Park Nannies, the Palo Alto Recreation Foundation, Allied Brokers, the Palo Alto Medical Foundation, the Lucile Packard Children's Hospital at Stanford, Hobees, the Palo Alto Weekly and Palo Alto Online.
Though pre-registration for youth groups has passed, individual kids who show up by 9:30 a.m. the morning of the parade can march in the "Kids on Parade" category.
