One of the largest picnics in California will take place Saturday, April 16, when tens of thousands of people visit UC Davis for its annual Picnic Day. Opening ceremonies for the daylong campus open house will begin at 9:30 a.m. on the north end of the Quad, followed by a parade through the campus and downtown Davis. "Students Shining Through" is the theme of this year's celebration. Among the highlights are a chemistry magic show, fashion show, police-dog agility demonstrations, sporting events, musical entertainment and departmental exhibits. Picnic Day is organized by a 12-member student board of directors, led this year by Erik Jarvi. This 81st annual open house event gives the UC Davis campus an opportunity to showcase its accomplishments, according to Jarvi.
