While other parts of the U.S. panic, the Bay Area revels in our multi-ethnicity. This Sunday, for example, you can cheer on the 40-foot long, gorgeously carved Dragon Boats each powered by 20 paddlers as they race against each on Lake Merritt in Oakland. In Japan Town on Sunday watch the astonishing things artists do with paper at the Origami Palooza Festival, which also includes a paper airplane contest. Enjoy a strong dose of Filipino culture at the Pistahan Parade on Market Street this Saturday, then visit 7 pavilions of crafts and foods at Yerba Buena Gardens. Or Sunday join the crowds in Golden Gate Park for the Ratha Yatra Festival of Chariots in Golden Gate Park. All events free.
