Just to erase any doubts that Spring has finally arrived you might want to wander over to the Cherry Blossom Festival the next two weekends in Japantown. There’s a parade on Sunday April 16 and the rest of the time there’s a full-on celebration with traditional food and music. Free. Prepare for crowds. Last year 200,000 people showed up. For a more serene take on this graceful culture there is always the Tea Garden in Golden Gate Park.
